Shared storage configuration on RedHat 5

Samshen — Tue, 12 Aug 2008 11:17:16 GMT

Hi,
I am using ReadHat 5 Enterprise version in two Proliant DL580 G5.
I have connected MSA2000 FC create the external shared array.
I have created by "Logical Volume Manager" utility three logical volumes.
There were created also corresponding directories:
/dev/VolGroup10/LogVol101
/dev/VolGroup10/LogVol102
/dev/VolGroup10/LogVol103

From the second server, from ""Logical Volume Manager" utility I can see all the volumes, but the directories on /dev are not created so I cannot mount them as raw partitions.
Please help me how to create the /dev directories.

Thank you

Shalom,

More details please.

Do you have GFS installed?

Are the volume groups in shared mode?

Appears to me that the second system might not see the disk at all.

hp_rescan a utility that ships with PSP, Proliant Support Pack can help clear up these issues.

Hi,
I ran successfully hp_rescan utility, but no change.
The second server can see the volumes only from "Logical Volume Manager" utility. From there there are displayed the corresponding paths:
/dev/VolGroup10/LogVol101 ...

but when I go on /dev I cannot find VolGroup10 directory (only /dev/VolGroup00, which is the internal disk).

Thank you

Do you have cluster suite? Is the clvmd service started?
