Looking for some opinions on replacing a couple undersized root disks on
an E5500.
Currently the system boots off an old storEdge array with a couple 4.2
gb drives. System is using Solaris 2.6 with VVM 3.0.
Here are the gotchas.
1. Array is full. No more disks can be added.
2. Root disks are VVM managed.
3. All avail slots in the 5500 are full.
4. Filesystems are UFS.
5. System hasn't been patched since 2000 or so.
6. Most filesystems are above 90% full
7. System is mission critical and cannot be taken out of service for any
length of time.
( Don't blame me I just started here )
It appears someone striped all the rootdg volumes over all 5 disks in
the array :-( So no mirroring is enabled.
The idea I have come up with is to add an old A5200 with a pair of 73gb
drives. Ufsdump the system to tape and restore to the 73gb drives. Then
grow the slices.
Being the best way to ufsdump a system is in Single user mode what
slices are available when your disk is VVM managed in single user mode?
My disk is sliced like so..
/
/usr
/var
/tmp
/opt
The other sad part is I don't have any test systems here @ work I can
play with these theories. All systems I have ever manager I always used
disksuite so it made backup
and recovery way more simple.
Thanks
Jeremy
