Hey all,
This is probably a dumb question but if I use the updatevv command to refresh a snapshot, does the Solaris MPxIO device name changes or will it stay the same?
Thanks

updatevv and Solaris MPxIO
Re: updatevv and Solaris MPxIO
Well, sadly, it looks like updatevv updates the VV_WWN which is super annoying and will in fact change the device path.

If you're still around...
I only update sets of VVs, so I use this command in a ksh script:
updatevv -ro -f set:${VVSET}
My WWNs and device paths get preserved on Solaris 10 using MPxIO.
Some of the help sections specify that when you create the initial snapshots, you should specify a high-number VV ID. Looks like the array uses the lowest free ID number when anyone creates new volumes/snaps. Combine that with the idea that refeshing snaps temporarily removes the snap VV. Sounds like you don't want those two things happening at the same time.
