SVM Soft partitions in a metaset- how to migrate ?
Hi Friends,
I need your assistance, could someone assist....
Scenario:- Solaris 10, with zones and mounted file systems, using SAN.
SVM with metasets on it configured soft partitions on the meta device.
These soft partitions are mounted and file systems are being accessed.
We are now trying to migrate/mirror these disks onto new one.
I was able to add a new disk into existing metaset, but couldnt perform any mirrors, sub mirrors out of the existing soft partitions. any pointers plzzz.

in this configuration you can not add a submirror because there is no mirror configured... when I create a diskset I allways use a oneway mirror (a mirror with only one submirror) configuration. with this config I can allways add a second submirror to duplicate my data.

thanks a lot dukenuke for prompt response. In this case what;s the best way to migrate the data ?? rsync ? tar/cpio ?? also the filesystems are mounted and in use constantly.

in your case a downtime (no access to the filesystems) is needed. i've good results with ufsdump/ufsrestore to duplicate filesystems. have a look at the manpage of ufsrestore for a good example of the command.
