Solaris mirroring / non-root disk

Hi Guys,

Need to add 2 disks into a JBOD array (3310).
Does anyone see anything wrong with my Procedure / Doco below?


1> Logon to system, check system logs for abnormal entries.

2> Make backups of related system files:
A>cp -p /etc/system /etc/system.backup.081505
B>cp -p /etc/vfstab /etc/vfstab.backup.081505

3> Insert drives into slots C3T11 and C4T11
4> Run commands:
A> #devfsadm -Cc disk
B> #prtvtoc /dev/rdsk/c4t9d0s2 | fmthard -s - /dev/rdsk/c3t11d0s2
C> #newfs /dev/rdsk/c3t11d0s2
D> #metainit -f d47 1 1 c3t11d0s2
E> #metainit d57 1 1 c4t11d0s2
F> #metainit d67 -m d47
G> #metattach d67 d57
5> Add following line to /etc/vfstab file:
/dev/md/dsk/d67 /dev/md/rdsk/d67 /dataset ufs 2 yes

Looks okay.

I have never used slice 2 (whole disk) with SDS, but it should work assuming the disks are the same and you already have a meta database. The syntax looks correct.

I would partition the disk so that slice 7 has all of the cylinders in it, and use it.

SUN dos not recommend to use slice 2 for general data storage.
Thats the reason why you cant partition slice 2 during solaris installation (the installer just shows you slice 1,3 and so on)

However, it should work at all.
