Hi,
Good day !!!
Is there any chance of data corruption of the tape drive or the hard disk if I apply metdetach in the multi-user mode and take a backup of the detached hard disk ?
Thanks

If it would leave you without a mirrored device i guess it might result in corrupted data, but that would require that the remaining disk have some hardware faults which wasn't detected previously..
If you don't want to take a backup of a live filesystem, you could use fssnap to take a snapshot which you can use for backup purposes..
.7/M.
depends on what's on the disk you're trying to backup.
If it's a database, then you'll still have the same-problem of backing up an open database.
If its the boot disks, then i'd metaclear the device first, then fsck it, mount it, then back it up. In reality though, a ufsdump of a live filesystem (despite how frowned upon it is) works 99% of the time.
Check what processes are accessing the disks intended to be backed up, and what you would want to be restoring from the backup.
The only way to know is test it and check results.
Unless you have three mirrors, then i guess it would be safe to break out one..
.7/M.
