Mount the San disk on Linux RH4 server

[Leah Chow]

Hello,

We just moved 100gb San space from one linux server to another, when i ran the df -k, i couldn't see the san disk on the second linux server.

Here is the result from fdisk -l command:


Disk /dev/cciss/c0d0: 146.7 GB, 146778685440 bytes
255 heads, 63 sectors/track, 17844 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

And the error messages from /var/log/messages are:

from the fstab file i can see this line:

/dev/VolGroupSAN-OraDb/LogVol-SAN-OraDb /laserfiche ext3 defaults
1 2

but when i go to /dev, i cannot find VolGroupSAN-OraDb.

Could you guys tell me which commands i can run to mount the san disk, do i need to format the disk?

thanks a bunch

Leah

[Steven E. Protter · Accepted solution]

Shalom Leah,

Choices:
reboot, see if the new disks are recognized.

Instal PSP for Proliant, all options.

hp_rescan
Scans the fiber channel and identifies new disks.

Yes, i know reboot will solve my problem, but i have to wait until Sunday to reboot the sever. alos i don't have hp_rescan command on my server.

thanks
Leah

PSP can be installed Leah, without a reboot.

Then you will have hp_rescan and be able to resolve this issue.
