How do I remove an auto raid cabinet?

[mike worrell]

HI guys,
We use to have 3 servers - x31 x32 x33 that were in a service guard environment. These boxes are no longer needed due to a merger a few years ago.
x31 was an application box, x33 was a database box and x32 was a failover box.
There is an autoraid cabinet (18gig drives in it and 2 controllers) in x33 and 2 in x32.
I've never worked with autoraid before, a vendor took care of this for us.
I need to disconnect the autoraids and totally shut down x31 and x33, we are keeping x32 to run omniback on, so all i need is the disks in the jamaica box for vol group vg00.

I have removed/deleted all logical volumes associated with the autoraid on x31/x32 and x33.
I reboot x31 and x33 just fine.
ON x32 during the reboot I get the message where it is changing vg00 and vg01 then it quits. If I powercycle the autoraid it completes the boot up process. If i disconnect the autoraid I quit at the same part and have to hook back up and power cycle. What piece of the pie am I missing?

Check for this volume group in /etc/fstab and /etc/lvmrc. It looks like it's still trying to activate it so you'll probably find an entry in /etc/lvmrc.

I think you 've not removed the VGs from those systems. You need to do that on x32 system. Find out which VGs were using the disconnected AUTORAID and remove or export those VGs from the system. If you need only vg00 on the system now, then remove all other VGs:

# vgexport /dev/vg01
OR
# vgremove /dev/vg01
# strings /etc/lvmtab - will tell you about all VGs configured on the system. Make sure you have only left with the one's you needed.

Since the box was in an MC/SG environment.. you should check /etc/lvmrc file as Pete suggests.

Look under the custom_vg_activation() section of the script. You may need to comment out the entries for custom_vg_activation then set AUTO_VG_ACTIVATE from 0 to 1.

Have you removed MC/SG or modified the config scripts to prevent it from running at boot?

hope this helps,

forgot to mention ...rather than edit the /etc/lvmrc back to default... you could just copy from /usr/newconfig/etc/lvmrc

i did strings /etc/lvmtab on x32
and it shows a volume group that i did delete.
/dev/orabackup

It's gone, how do I get it out of lvmtab
when i do the vgexport it gives message about looking for lvm_lock
???

[Pete Randall]

Mike,

copy /etc/lvmtab /etc/lvmtab.old
vgscan -a

That should straighten out the lvmtab issue.

Thanks to all. I just got the /etc/lvmtab on x32 to show as I need. I had to move the /etc/cmcluster/lvm_lock file out of the way to get vgscan to work.
Should I just unhook the autoraid cables now? or is there other items I need to do?

Thanks
Mike

Hey Mike!

Success at last!

It sounds like you're ready to unhook the cables and kiss it goodbye. Hopefully we haven't missed anything.
