Current setup is an Ultra 80 running Solaris 8.
The System disk is currently mirrored using Disksuite, in addition I
have an external disk pack attached which contains a RAID 5 set also
under the control of disksuite.
My state databases are laid out as follows:
flags first blk block count
a m p luo 16 1034 /dev/dsk/c0t0d0s6
a p luo 1050 1034 /dev/dsk/c0t0d0s6
a p luo 2084 1034 /dev/dsk/c0t0d0s6
a p luo 16 1034 /dev/dsk/c0t1d0s6
a p luo 1050 1034 /dev/dsk/c0t1d0s6
a p luo 2084 1034 /dev/dsk/c0t1d0s6
a p luo 16 1034 /dev/dsk/c1t1d0s0
F M p unknown unknown /dev/dsk/c1t2d0s0
a p luo 16 1034 /dev/dsk/c1t3d0s0
/dev/dsk/c0t0d0s6 - first harddisk
/dev/dsk/c0t1d0s6 - second harddisk
/dev/dsk/c1t1d0s0 - first drive in RAID 5 set
/dev/dsk/c1t2d0s0 - second drive in RAID 5 set
/dev/dsk/c1t3d0s0 - third drive in RAID 5 set
My question is as follows:
I want to replace this Ultra 80 with another Ultra 80 system that has
been installed with Solaris 9. This system has its main hard disk
mirrored with Solaris 9 Volume Manager. What would be the procedure
one would follow to disconnect the RAID 5 pack from the Solaris 8
machine and get it up and running on the Solaris 9 system?
Giving the fact that there would be two copies of the old Disksuite
state databases on the disk pack and there would also be Volume Manager
databases on the mirrored internal disks. I'm also aware of the fact
that Volume Manager has changed things a bit where as the state
databases now take up 8192 blocks compared to that of Disksuite's 1034
blocks.
I'm hoping there is a solution of other than just blowing the RAID 5 set
away, recreating and restoring the data.
Thanks,
---Andy
