SAM doesn't display an VG/LVOL info

[JaeKennedy]

Hello, everyone --

I'm having an issue on my Development server (rp7420 hpux11.11) where SAM is not displaying any volume group or logical volume info. I can get the info I need via command line, but when I try to open either "logical volumes" or "volume groups" in SAM I get a message saying that there are currently no volume groups set up on the system (see attached). I've gone through the process of copying out the lvmtab and running a vgscan to recreate, but it still doesn't see any defined volume groups. Even after a full system reboot SAM doesn't see them.

Has anyone ever seen or heard of this before? Any suggestions on what else I may be able to try in my troubleshooting? Any feedback is much appreciated!

Cheers,

Can you run "vgscan -p -v" and see if you have some errors or not? It sounds like your /etc/lvmtab does not match your current VG configuration.

Take a look at the SAM log using
# samlog_viewer -tn >/tmp/samlog.txt

SAM uses a script called "vginfo" located in
/usr/sam/lbin. Run this script and see what it gets using
# /usr/sam/lbin/vginfo -v

Check volume groups are activated or not.
#vgchange -a y
Are u using cluster on your server.

Is it just sam ? or is it more serious?
can you check your current and old lvmtab:
strings /etc/lvmtab
strings /etc/lvmtab.old ( or whatever you named it before the vgscan)

does it show the vg's ?
if not the system can not see the disks as well ? ioscan -fnC disk ...
does it show disks of the other VG's?
if not check SCSI/fiber connections..

regards.

Sorry for the delay in response...out of the office.


To answer all the questions:

* /etc/lvmtab shows all the correct vg's and disks
* ioscan shows all disks
* vgdisplay/lvdisplay displays all the correct info

However, Sameer -- the "vginfo" command gives this error:

# /usr/sam/lbin/vginfo -v
vxvm:vxprint: ERROR: IPC failure: Configuration daemon is not accessible
vxvm:vxdisk: ERROR: Cannot get records from vxconfigd: Record not in disk group

Which is weird, because we're just using LVM...not VxVM.

If the /usr/sam/lbin/vginfo -v,
just displays the error related to vxvm and not the other VGs, then therein lies your problem (or rather SAM's problem).

The vginfo is a script that uses vgdisplay, pvdisplay and other lvm(7) commands to gather the required info.
What is the SAM patch level on your system? Is it the latest?

Thanks for the responses, everyone. I think I'm going to open a case with HP to try and get this resolved.
