creating cluster aware lockdisk vg

galenr — Wed, 05 Feb 2003 16:39:34 GMT

I have created a /dev/vglockdisk on c8t0d0 on my primary server.I have done the same on c5t0d0 on my client server,and subsequently completed or so I thought my cluster configuration. When I initiate cmcheckconf, It tells me the the first cluster lock volume grp.(/dev/vglockdisk) needs to be designated as a cluster aware vol group.How is this done? Need I export /dev/vglockdisk ? How do I make it cluster aware?

thanx in advance....

Hi,

Make sure you added /dev/vglockdisk in /etc/cmcluster/cmclconf.ascii (your cluster ascii file).

If you are setting the cluster for the first time, it should take care of it automatically. Otherwise run

vgchange -a n vglockdisk
vgchange -c y vglockdisk

This should make it clusteraware.

so have you created this on a shared vg?
if so, ensure you do vgchange -a y on the node on which you will do the cmcheckconf/cmapplyconf.

Hi!
Make sure vglockdisk vg are identical on
both mashine. You need to create vglockdisk
on system1 and then use correct technics
to distribute it to system2:

system1#vgexport -m map-file ...
system1#rcp map-fle to system2 ...
system2#vgimport -s -m mapfile ...
"-s" option is important!

Then you can go on.

I thing it only need to add vglockdisk to
cluster ascii-file. The command cmapplyconf
sets flag "-c y" to all vg's, figured there.
