How to connect disks from iSCSI array and from SAN network. I found that it is possible to establish iSCSI on solaris by using COMSTAR [url]
Questions: Could you give me some tutorial how to do this ? I don't have of course SAN network in my home lab and iSCSI array too, is there some way I can simulate this on VBOX or VMWARE ?
I am running RHEL5.5 its a fresh install and we are testing Xen Virtualization. We are wanting to use our iSCSI SAN for the VMs. I have created the initiator iqn, and discovered the target address. We are connected to the target, but there is no new block device in /dev.
[root@xxxxxxxx etc]# netstat -a | grep iscsi
tcp 0 0 *:iscsi-target *:* LISTEN
tcp 0 0 xxxxx-netapp.okc-:44840 xxxxxx-iscs:iscsi-target ESTABLISHED
tcp 0 0 *:iscsi-target *:* LISTEN

I have a server wich is connected to an iSCSI storage and gets harddisks from this storage. Sometimes I have to add new disks to this server. Everytime I add a disk and make an /etc/init.d/iscsi restart on the server the disks don't have the same device name as before the iscsi restart.
It should be possible to gave the disks persistent names using udev rules. Now I tried to create different rules in "/etc/udev/rules.d/99-static-iscsi-names.rules" e.g.
# /dev/sdc
KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -s %p",RESULT=="360a98000503355344c4a576864467877" NAME=="sdc%n"
In "/etc/rc.local" I added "/sbin/start_udev" and in "/etc/scsi_id.config" I added the line "vendor="NETAPP",model="LUN",options=-g"

I have never done this before but stood up a new Debian (testing) x64 system. It only has 146GB available for RAID1 so I created a 500GB iSCSI LUN on my NAS device on the network and am really confused how I can attach my Debian to the iSCSI LUN I created. Right now the OS is installed all locally on the machine but I would like the iSCSI LUN to be the /home directory for mail storage. Is this possible or do I need to mount the LUN to a newly created folder / mount point that is locally attached?

When i give the following command iscsiadm -m discovery -t sendtargets -p 192.168.2.13it only gives me one line output which is:192.168.2.13:3260,1 iqn.2006-01.com.openfiler:tsn.03821172572cNone of the mapped LUNS gets identified neither it shows me any message that it is connecting. I have setup CHAP in openfiler to accept an incoming user plus gave access to my OEL server.Any feedback is helpful. If you need the contents of /etc/iscsi/iscsid.conf file let me know

View 5 Replies View RelatedI have servers which contain SATA disks and SAS disks. I was testing the speed of writing on these servers and I recognized that SAS 10.000 disks much more slowly than the SATA 7200. What do you think about this slowness? What are the reasons of this slowness?
I am giving the below rates (values) which I took from my test (from my comparisons between SAS 10.000 and SATA 7200);
dd if=/dev/zero of=bigfile.txt bs=1024 count=1000000 when this comment was run in SAS disk server, I took this output(10.000 rpm)

I have/had a PC with several hard drives, and a mix of ubuntu and windows on multi boot.The old boot drive died screaming, and I need to start again. (But my data is safe! yay!)
Is there anything special about which drive can be the main drive to start booting from? Or to put it another way, can I install to any of the other 3 and expect it to work, or do I need to switch them around so a different drive is on the connections for the recently dead one?
I have two internal harddisk. Harddisk 1 has ubuntu, fedora installed and harddisk 2 has ubuntu installed. I normally connect either one, and use it. How can i always keep connect both harddisks, and at the start, select from which harddisk to boot? Or it's not possible?

Then I unplugged it and found that I have another file to upload so I plugged it back in. However this time it's not assigned a partition (last time was sdb1) and I can't mount it anymore. I think the USB key is recognized and the driver is installed properly:

View 5 Replies View RelatedI did a yum install libxml2 then later had to do a yum remove libxml2
on my rhel5.5 machine. During the course I answered 'y' to one of the questions asked, which may have lead to the problem I'm about to describe - I don't know because I can't reproduce the problem at the moment.
After doing the 'yum remove libxml2', which seemed to complete successfully, I tried to do a 'yum search <some other package>' and a 'yum install <some other package>' - both commands failed. The error message I get is
[root@server etc]# yum search libxml2
bash: yum: command not found
[root@server etc]# which yum
/usr/bin/which: no yum in (/usr/kerberos/sbin:/usr/kerberos/bin:/usr/bin:/bin)
I'm afraid during the 'yum remove libxml2' I must have removed some essential system libraries and applications, including yum.
