Hello Forumers,
any thoughts on this:
Assume someone took the disks / LUNs under control of SVM. STMS is not active therefore the boot volume might be called: /dev/(r)dsk/c1t0d0 and some FC attached LUN (2 paths) may appear as: /dev/(r)dsk/c2t5WWNNd0 and /dev/(r)dsk/c3t5WWNNd0.
The file /etc/vfstab would of course refer to objects such as /dev/md/(r)dsk/d20 or similar. Using command metastat would allow to show the association between /dev/md/(r)dsk/dN and /dev/(r)dsk/c1t0d0 and /dev/(r)dsk/c2t5WWNNd0 or /dev/(r)dsk/c3t5WWNNd0, respectively.
Now the admin would decide to enable STMS, so the boot volume might suddenly appear as: /dev/(r)dsk/c4t2000000....d0 and instead of two the two /dev/(r)dsk/c2t5WWNNd0 and /dev/(r)dsk/c3t5WWNNd0 (from above) one would only see a STMS metadevice , i.e. c4t6.....d0.
Would SVM recognize this modification automatically (as the respective device / metadevice association from above would cease to exist)? Or is there the need for explicit activity, and if so: what?
Thanks. Cheers dj600stoxx
