Unable to create cluster config file (11.16)

[Ra Jose]

I have 2-node SG cluster (11.16). My cmclconfig.ascii file is missing. I do have the binary one. I tried creating ascii file from one node -
node1# cmgetconf -v -c cl_name cmclconfig.ascii

The above cmd gave errors and ascii file was not created. Here are the errors.

Warning: Volume group /dev/vgTUP is configured differently on node node1 than on node node2
Warning: Volume group /dev/vgTUP is configured differently on node node2 than on node node1
Error: Volume group /dev/vgTUP on node node1 does not appear to have a physical volume corresponding to /dev/dsk/c8t11d3 on node node2 (276328611143731522).
Error: Volume group /dev/vgTUP on node node1 does not appear to have a physical volume corresponding to /dev/dsk/c10t11d3 on node node2 (276328611143731522).

Can someone give what problems I am having?
Thank you all for your replies.

The /etc/lvmtab on each node should contain a list of every disk/LUN that is in the volume group. Apparently, c8t11d3 and c10t11d3 are listed in lvmtab on node1 but are not listed in lvmtab on node2.

Perform an ioscan to insure the system creates disk special files for all disks that it discovers. If the disks still do not show up, look at the array or zoning software that might prevent those LUNs/paths from being seen by node2.

If the special files exist, use
# diskinfo /dev/rdsk/c8t11d3 on node2 to verify the disk is accessible. You should see information about the disk/LUN.

When you are confident that the disks are present, re-import the volume group.

If you are not certain of the disk paths that belong to vgTUP on node2, create a map file that contains the VGID at the top thus:

node2:
$ vgexport -pvs -m vgTUP.map /dev/vgTUP
$ ll /dev/vgTUP/group (record the minor number)
$ vgexport vgTUP (it must not be active on node2)
$ mkdir /dev/vgTUP ; mknod /dev/vgTUP/group c 64 0x0N0000 (where N is the minor number)
$ vgimport -vs -m vgTUP.map /dev/vgTUP

Inspect the resulting /etc/lvmtab:
$ strings /etc/lvmtab
Look for c8t11d3 and c10t11d3

When you have determined those paths have been added, do the cmgetconf again.

Thank you Stephen for your help. As you said, the lvmtab on node1 and node2 are different. One has these devices but the other does not.
