Hello,
while testing some features around LSM i noticed a strange behavior,
which someone might possible explain:
i created a LSM-disk using "voldiskadm rz24" (in fact this is a disk
originating from an EMC 3700 Box) as a member of a diskgroup called
"infdg". Then i configured some subdisks out of rz24 to build some
plexes which were brought up as a mirror for several already existing
volumes of this diskgroup. Up to this point - including mirroring -
everything worked as expected.
Then i deported the mentioned diskgroup using "volplex deport" and all
the other stuff like stopping the volumes etc. before! Next step was to
change the scsi-controller to which the rz24 disk was connected, so it
came up as rz16 after a reboot. After giving a "voldisk define rz16" and
a following "volplex import", LSM complained that no configuration
records could be found on disk! A "voldisk list rz16" made clear that
the configration copies were missing! Why?
