Hi,

Can I increse /opt partition under veritas

having /opt as a separate filesystem isn't supported by Solaris. You can have stuff under /opt (e.g. /opt/coolstack) as a separate filesystem but putting /opt separate will cause problems.
This isn't theoretical. I tried the same thing and it worked for awhile then it didn't and the system was in single user mode for agonizing time while I frantically remounted /opt as /a and moved it's contents back to the root filesystem.

/var as a separate filesystem is well-supported. There was a bug for awhile but it's fixed.

I had a trick that fixed this a long while ago.. I did have /opt as a
vxvm partition, but to avoid the catch-22, I mirrored all the /opt/VRTS
stuff to the root partition underneath it. It's hackish, but it worked.

This is still not a supported configuration. All you've done is let VRTS find it's drivers. You still have all sorts of stuff that the OS wants but which is not on the root. Having e.g. /opt/SUNWexplo/output on a separate volume is fine and probably a good idea if you're crunched for space on root since Explorer will make a gigabyte of junk if things go awry. But the the /opt/SUNWexplo belongs to a package in the package database. The OS will have conniptions. At a minimum, Live Upgrade won't work right. Under certain kernels, it won't boot.

Was the issue with /opt being an inherited directory in a Zone? That is
documented in the Install Guide for SF 5.0 MP3

yes, the boot failure was for a zone which inherited pieces of /opt (/opt/csw, /opt/netbeans...). don't inherit-pkg-dir /opt though, then you can't ever add your own directories to /opt in the zone.
Nonetheless as I said /opt on a separate filesystem is not supported by Sun. It will make lucreate fail among other things.

Can you do it ? Yes

Should you do it ? No

VM will let you grow any volume BUT since your /opt on slice 5 it WILL NOT resize the underlying partition.

So if you need to un-encapsulate you will end up with /opt being the size of s5, NOT what you resized it to under VM.
