General :: Migrating From SCSI To SAS?
Oct 20, 2010
I have a Linux system running on an older Sun V20z. The drives are mirrored in a software RAID1. The motherboard has interfaces for only IDE and SCSI. The system is old and is no longer able to handle the load we're putting on it. I also have a much newer Sun X4100. This system is presently unused and has a pair of SAS drives in it. The new server only has SAS and SATA connections on the motherboard, though. I'm trying to think of the best way to clone the V20z over the X4100. I don't mind breaking the mirror knowing I can re-establish it later. I prefer not to do a fresh OS install followed by a tape restore. I would much rather break the mirror and clone one of the SCSI drives the SAS drive. I do have a USB to SATA adaptor for migrating external drives. Anyone know if this will work with a SAS drive? Any pointers on the best way to migrate this? I'm thinking even if the cloning is successful, I'm going to have to much with GRUB to get it to boot from the SAS drive?

Some of our workstations have LTO's attached and they seem to drop off every now and again, the only thing which picks them up again (besides a reboot) is the famous rescan-scsi-bus script from here
The thing is that I'd like non-root users to be able to run this script, which in turn needs root to /proc/scsi/scsi

i m facing same error in most of the HCL servers. the problem is that it throws error while booting and sometimes not throws error. the error is :-
Feb 13 13:17:25 fe13s kernel: Adapter 0: Bus A: The SCSI controller was reset due to SCSI BUS noise or an invalid signal. Check cables, termination, termpower, LVDS operation, etc.
Feb 13 13:17:30 fe13s kernel: Adapter 0: Bus B: The SCSI controller successfully recovered from a SCSI BUS issue. The issue may still be present on the BUS. Check cables, termination, termpower, LVDS operation, etc
Feb 13 13:29:15 fe13s kernel: Adapter 0: Bus B: The SCSI controller successfully recovered from a SCSI BUS issue. The issue may still be present on the BUS. Check cables, termination, termpower, LVDS operation, etc

In my understanding, the way /proc/scsi/scsi gets populated, /proc/paritions also gets populated in the same fashion. i.e. the description for first entry of /proc/scsi/scsi can be seen in the first entry of /proc/partitions and same for rest.
So, With this assumption, in my project, I used to relate first entry of /proc/scsi/scsi with first entry of /proc/partitions to get its total size and same for all entries.
But, I observed some differences in following scenario, where
1) The first 4 entries in /proc/scsi/scsi are SAN luns attached to my system and for which the actual device names in /dev/ are sda,sdb,sdc and sdd.
2) The last 4 entries are the internal HDDs on same system. In /dev/, their respective device names are sde,sdf,sdg & sdh.
(Output attached at end of the thread)
But in /proc/partitions, the device order is different.
You can see their respective sizes in /proc/partition output as well.
So, my question is, in this particular scenario, I can't relate the first entry of /proc/scsi/scsi with first entry of /proc/partition. i.e. scsi0:00:00:00 is not /dev/sde, because it is actually /dev/sda.
It seems that my assumption is wrong in this scenario.
Is there any way or mechanism to figure out actual device name for an entry in /proc/scsi/scsi in /dev/ directory?
How can my application should relate /proc/scsi/scsi entries with their respective device names and sizes?

When I enter "cat /proc/scsi/scsi" I'm returned with "cat: /proc/scsi/scsi: No such file or directory". I've tried this on two different installs on two different machines.

Migrated my wife to Linux when her old computer broke. She has an old iPod (one of the first ones to show video) that has music and playlists on there. I know how to sync podcasts to my iPod shuffle with gPodder and GTKpod. But how would I sync up files with her iPod? Also, what program would I use to automatically sync the iPod with any music dropped into her Music folder? This should be as painless as using iTunes or she won't do it.

I'm running Windows 7 (on my Acer Extensa 7630EZ) at the moment but I realized that I'm using mostly Linux programs (including the Linux shell through Cygwin) so I'm considering migrating to Linux (probably OpenSuse?). While this would certainly make my life easier, I'm also used to a few things on Windows I don't want to give up: Drivers.
I have a Canon PIXMA MP970 network printer and scanner the driver whereof has a GUI on Windows. I bet that even if I ever manage to get the printer to work on Linux, the GUI will be missing, so I will not have access to any of the options. (For me, this is a real reason for sticking to Windows, unfortunately.)
- Windows Media Player. Although it's not as universal as other media players (VLC), I got used to it because of its well-organized media library and the ability to include a SMB server in it or use a network media library.
- Adobe CS5. I don't know if it works with WINE, but I hope so.

The development sever of the project i am working on, currently has the source codes on a UNIX HP_UX operating system with oracle version 9i. it needs to be migrated to LINUX redhat OEL rel 5, with oracle version 10g . As i am a complete newbie to this, Could anyone please tell me what are the important things to be done as a part of migration, to make the new environment complete? i have transfered the source codes to new server, installed the required compilers and have almost completed with oracle 10g installation.

In the past, I've deployed new 64 bit systems and I've worked on and developed on 64 bit systems. But until a week ago, my workstation was a 32 bit system. Now, it is a 64 bit quad core Phenom II system, and I suppose I need to start the migration to 64 bit Linux. I do not want to blow off my system and rebuild it. This particular system dates back a decade and through many many updates. There is some digital debris in it, but there is also a fair amount of customization that I have implemented either for my own purposes or for customers, and to lose that customization would represent a headache for me.
What I want to do is install a 64 bit system over top of the 32 bit system. It is my hope that doing this would install the necessary 64 bit libraries, while not impacting the existing 32 bit libraries (except with some possible symlink problems). I then, hopefully, could boot into a 64 bit kernel while still running 32 bit programs. Is this feasible? My backup system is comprehensive; I COULD just try it and back up if my system became hosed. But I'd rather not; I have a lot of work to do and I'd rather not learn by doing in this case.

We are in the process of analysing the possibility of migrating our application from HP-UX unix operating system to Linux operating system.
1)In our application, most of the source codes are written in C, C++ languages.
2)We are using aC++ compiler in current HP-UX opertaing system.
3) And also we have 400 shell scripts.
4) Using Oracle 10g database

I have installed an old HP Scanner on my Fedora 11 system, and it works great. The scanner is connected through a SCSI, and it gets recognized at boot time if the scanner is ON. However, if the scanner is OFF, I need to turn ON the scanner and reboot the workstation for the SCSI devise to be recognized. Is there a way that I can rescan the SCSI devise without rebooting?

Im currently using windows 7 and I want to shift for Linux. So i thought to start from Mandrake-free. My current filesystem is NTFS which full of windows extension documents. Those capacity is almost 200GB.but im not in a position to backup everything. i got to know from forums that linux perform well in ext3 file system. so i wish to go for ext3. is there any ways to shift FROM,win7 TO mandrake AND
ntfs TO ext3 WITHOUT BACKING UP CURRENT DOCUMENTS ASWEL AS WITHOUT LOOSING ANY OF MY WINDOWS BASED DOCUMENTS.? and i got to know that in a single harddrive(eg 250GB), Its not good for the harddisk to have different type of partitions (eg 50gb of ext3 and 200gb of NTFS). if i used like this will my harddisk got crashed? because this happened to me 4 years ago when i was trying to install winXp(in ntfs) and Redhat(in ext2) in the same hardisk. i was working initially. but was in 2 days that HDD got crashed.

I am attaching a LTO-3 tape drivce into my RHEL5 linux machine. Every time i used to restart my machine to detect the tape drive is there any way to rescan the buses to detect the newly attached scsi devices. In solaris "devfsadm" and "iostat" is there. I need the same kind of thing in linux.

I have a virtual machine with Solaris 10. On this virtual machine I have to configure an iSCSI initiator.
The problem is that i have no physical SCSI devices to connect to my LAN
Therefore I have to create a Virtual SCSI device on my host laptop and configure it as an iSCSI server (iSCSI target) and share this virtual disk on the LAN.

I have one scsi storage array, JetStor SATA 416S,split into 2 halves. each is RAID5 12TB. Is it possible to dedicate each half to a different rhel5 server. I have "lsi22320-r" ultra230 dual channel scsi adapter in each server.
The first server sees the 2 halfs however the second server doesn't on the first server:

I am testing PCLinux 2009.1 prior to installing. My desktop currently runs on ME and has been out of use for some time. It still works however and I can still get online. I'm currently using a laptop running XP. I would like to make use of my old desktop and tried to test PCLinux 2009.1 today. I followed the instructions obtained online and booted from the Linux cd. The pc booted up ok and displayed the first screen allowing me to select the "Live CD" option. After enter my system hung up at "Probing SCSI Devices:Segmentation fault".

So I have a system that is about 6 years old running Redhat 7.2 that is supporting a very old app that cannot be replaced at the moment. The jbod has 7 Raid1 arrays in it, 6 of which are for database storage and another for the OS storage. We've recently run into some bad slowdowns and drive failures causing nearly a week in downtime. Apparently none of the people involved, including the so-called hardware experts could really shed any light on the matter. Out of curiosity I ran iostat one day for a while and saw numbers similar to below:
[Code]...
Some of these kinda weird me out, especially the disk utilization and the corresponding low data transfer. I'm not a disk IO expert so if there are any gurus out there willing to help explain what it is I'm seeing here. As a side note, the system is back up and running it just runs sluggish and neither the database folks nor the hardware guys can make heads or tails of it. Ive sent them the same graphs from iostat but so far no response.

I am trying to install Ubuntu ver.10.10 server on HP DL360 with 2 internal 36GB untra3 scsi drives. The installations seems to have gone fine but upon booting, the OS is stoping at the BusyBox menu with initramfs prompt. None of my boot or root filesystems is mounted here so I can not go further. I've searched all over the net for answers but nothing seems to work.

Install Linux (Fedora) on a laptop, that has XP right now (removing XP completely). Preserve the contents of "My Documents" on the same hdd while installing linux on my laptop (external hdd unavailable) The installed Linux to use full hdd space, contents of "My Documents" to be in /home, and have no leftover partition, that was used while migrating. It would be nice to have a regular hdd scheme after all of that.

I'm in the process of duplicating all the data from my existing filesystems to a new storage solution. I know it is not recommended to do so but this will be a *lot* faster then having to reinstall and reconfiguring the system from scratch...I've synchronized the filesystems using rsync, used the following command line for that:
Code:
rsync --recursive --acls --xattrs --delete --force --one-file-system --links --perms --owner --group --stats --specials --devices --human-readable / /mnt/sde1
rsync --recursive --acls --xattrs --delete --force --one-file-system --links --perms --owner --group --stats --specials --devices --[code]....
To make sure all data is mirrored properly, the next step is to boot into a live system and rerun rsync to copy any previously locked/altered files to the new storage. After moving this, I know I have to edit /etc/fstab on the new storage to make it match the proper UID for the drives. I also have to update grub and install grub into MBR of the new storage.

I recently converted from MS 2003 to Ubuntu 10.04.1 and i wish to change the filesystem of all my data disks from NTFS to EXT but i have run into a problem. When i delete the old nfts partition and create an EXT4 partition, i can see that on the newly created partiton the used space is about 20gb. I used gparted for this. I have read that EXT reserves some space for root, but since all the disks i wan't to convert is only used for data and not OS, i see no need for the reserved space. I found some commands to turn of the root space but that did not work so i changed to resiserfs but that very slow, unstable and under limited development.

Now can I move that server to a machine with Pentium D Dual Core, 1 GB DDR2 without having to install anything.
If I do need to install a new version, can I atleast move all System / Network Configuration from old to new server ?

I've been looking at Gnome 3 and the Gnome Shell and I don't like what I see. The Gnome devs are taking things in a direction I don't like, giving us new ways to do things that don't interest me and making them mandatory. AFAICT, in the long run there's no real way to configure things to work the way I've been doing things for the last fifteen years. This is not a rant, not (mostly) a complaint, merely an observation. Clearly, I'm not part of their target demographic and I doubt that I'd want to be under the circumstances.
To me, that means it's time for me to move on and try something different. After some careful research, I've migrated my laptop to XFCE and am very happy with it. Now, I'm about to do the same to my desktop. This leaves me with an interesting question: what's the best way to remove Gnome from my two machines without removing any support needed for various programs that I'm accustomed to using and expect to continue using?

I am now using SuSE 11.1 with KMail 1.9.10 (KDE 3.5.10 "release 21.13.1" open SUSE). My intention is to do a clean install of 11.4 from purchased DVD and then migrate (import) all of my personal files from a backup. I have not yet seen either SuSE 11.4 or KDE4, so I am unfamiliar with any changes to the folders and files, how they may have been named, where they're located in 11.4, etc. Inoder to copy my backed up KDE 3.5 KMail into the newly installed SuSE 11.4/KDE4 KMail, will the following folders and files go into folders and files named the same in 11.4/KDE4, or will the folders and files for the new KMail be named differently and/or be located differently?
/home/<my name>/.kde/share/apps/kmail (my e-mails)
/home/<my name>/.kde/share/apps/kabc/ (address book)
/home/<my name>/.kde/share/config/kaddressbookrc (address book settings)
/home/<my name>/.kde/share/config/kmailrc (kmail settings)
Are there any issues I need to be aware of in migrating the KDE 3.5 Kmail materials into 11.4/KDE4? Or will this be as simple as when I upgraded from 11.0 to 11.1?

i have recently started using kde 4.x. I am trying to find out where are some kde 3.x feautures and how i can use them under kde 4.x
To be more specific:
A)IN kde 3.4 i was using multiple desktops. I still remember that i could see in my taskbar a preview of every virtual desktop and what applications are currently open on each desktop. In kde 4.x these icons are so small so i can't see any preview so there are not as useful as in previous verions
B)In kde 3.x i could easily create desktop shortcuts by dragging and droping icons. Right click on desktop gives no such an option.
C)What is the plasma dashboard(something like that)? Actually there is a small shortcut in the taskbar that seems to be working like the old one show desktop shortcut.
