Question:
I have a Sun Storedge D1000 mirrored RAID (0+1) with Disksuite on a Sun
Ultra 80, Solaris 7. The mirrored RAID has 12 (6 on each side of the
mirror) 18GB IBM Ultrastar Ultra3 SCSI disks Model DDYS-T18350 10K RPM.
There is a system disk on each side of the mirror (18GB) which I want to
leave as is and replace the remaining 10-18GB disks with 36GB disks using
Disksuite. The 36GB disks are SEAGATE Cheetah Model ST336607LC 10K RPM.
Since the architecture (geometry) of the Seagate disks is different than
the IBM Ultrastar can I use Disksuite and break the mirror on one side,
replace the 5-18GB IBM disks with the 36GB Seagate disks and resync and
then growfs the 36 GB disks first on one side of the mirror and then
repeat the process for the other side of the mirror or do I have to use
Disksuite only to configure the new 36GB disks on each side of the mirror
and then restore all the user data from backup tape since the architecture
of the 18GB and 36GB disks is different ? Can you outline the steps that
need to be followed to accomplish the disk replacement ?
Thanks, I will summarize.
