Re: vgchange: Too many links
there are missing disks in your vg, eiter the whole disks or the paths.
After vgchange -a y, are you able to mount lvs?
You can compare, vgdisplay o/p with lvmtab.
Thanks,
Vivek

Re: vgchange: Too many links
vgchange is not able to find this /dev/dsk/c9t0d4 disk...
It appears that u r using multipathing and one of the path is not working...so u need to verify whether this path exists using strings /etc/lvmtab...may need to check cable connectivity from SAN

As some path are missing, vgchange is not able to attach another path of the same disk on SAN,
Was there any changes on SAN cable connectivity???
U can either correct the SAN connectivity issue or remove these extra paths from VG by removing corresponding disk paths from VG using vgreduce

Re: vgchange: Too many links
displays whenever there is discrepancy with the multiple paths to the same PV.
Run vgscan -v -p -a ( -p is in preview mode )
to see if it`s able to scan the missing links.
If it able to scan all the links then take backup of the old lvtab file and replace it
with the new one created by running vgscan -v -a. ( not -p )
Thanks

Re: vgchange: Too many links
check vgdisplay noradata for Max PV and
Cur PV
if both are equal vgreduce -f vgname (noradata)should fix the issue.
if MAX pv and Curr PV differs you need to verify disks availality on server.
