There were still a few bugs in the SVM script that I was tweaking the other day, but I got them worked out, jumpstarted Lumana, and things are pretty good now.
The new SVM script creates MD device names based on the raw devicce name of the slice and only deals with mirrored setups:
cNtXdYsZ becomes dXZ, throwing out the controller number (we’re assuming that all install disks are on the same controller) and the disk LUN number (we’re assuming that there’s only the one). So a mirror of c1t0d0s7 and c1t1d0s7 has submirror devices of d7 and d17. The meta device container for the two is taken from 7 plus the target number of the second disk: here, 7+1, and then the slice number is the ones place. So the container for this would be d87.
I did this for Lumana, because it came with 4 disks, and I wanted to mirror the second pair as well. They’re on c1t2d0sN and c1t2d0sN, so they’re made of meta devices d30 and d40, with a container of d100 (only the first slice, 0, is used).
Need to add NetBackup and possibly the Forte compiler set to Lumana, and I’ll be done with it.
