Sun Cluster 3.0u1: replacing a mirrorset
- From: kev@xxxxxxx

Hello all,
I am looking to either grow or replace an existing mirrored diskset on our
Solaris 8 Sun Cluster 3.0u1 disksuite-based cluster.
I am trying to follow the guide at
http://www.sun.com/bigadmin/content/submitted/luns_diskset.jsp but it is
very confusing, and it seems incorrect, or not appropriate. The syntax in
line 8 is incorrect and to add a single volume to a cluster filesystem seems
a bit odd, I'd expect it to be mirrored.
So far I think I need to:
- insert the new disks into each array.
- run devfsadm
- identify the new volumes
- run 'scgdevs' and 'scdidadm -r' on both nodes
- partition the disk?
Then I get confused. Can I then just add the disks into the group with
'metaset -s <setname> -a <disknames>' and then attach them to the existing
mirror and sync them up, followed by removing the originals and then running
growfs?
I will summarise.
Thanks,
Kevin
