Solaris

All,

Is there a way to RAID the disks in Solaris 9? Solaris 8 provided DiskSuite for mirroring disk drives. Is there a GUI for DiskSuite in Solaris 9?

Thanks,

Mike

See the info on Sunsolve
and Solaris Management Console (metatool was incorporated/replaced into it)

In Solaris 9 the Solaris Volume Manager is your tool for Software RAID.

An quick howto for mirroring your system disk to the 2. disk.

1.Disk : /dev/dsk/c0t0d0sx

Slices: c0t0d0s0 /
c0t0d0s1 swap
c0t0d0s5 unassigned (128MB)
2. Disk /dev/rdsk/c0t1d0sx

First we must get the PArtition Table from the first disk to the second:

prtvotc -sh /dev/dsk/c0t0d0s0 > /tmp/disk && fmthard -s /tmp/disk /dev/rdsk/c1t0d0s0

Then we create the RAID Databases:

metadb -a -f -c3 c0t0d0s5 c0t1d0s5

Initalize the raid devices (slices)

metainit d10 1 1 c0t0d0s0
metainit d11 1 1 c0t0d0s1

2.disk

metainit d20 1 1 c0t1d0s0
metainit d21 1 1 c0t1d0s1

Create the mirror for the root slices:

metainit d0 -m -f d10
metainit d1 -m -f d11

Run a "metaroot" command

Edit the /etc/vfstab to:

the swap and root slice must be changed to "dev/md/dsk/d0 and for swap /dev/md/dsk/d1 you also have to change the /dev/rdsk path.

run :

dumpadm -f /dev/md/dsk/d1

REBOOT

Attach the second disk to the mirror:

metattach d0 d20
metattach d1 d21

You can view the status of your raid with "metastat"

Run a "metastat | grep done" to see how far your sync is.


Hope this helps
