moving /opt to SVM RAID-5?

I know, I know; never make changes on Fridays. But this looks so easy to fix...

Our V-880 is as a master/media Veritas NetBackup server. The /opt file system
has run out of room due to /opt/openv/netbackup/db/images/[client] subfolders.
Since /opt was originally sized to 7-GB, we plan to migrate /opt to a larger
location.

Fortunately, we have 3 unused 72-GB drives in the 880. Our plan is to use the 3
drives to create a ~60-GB SVM/disksuite RAID-5 volume for /opt. (The other
space on the 3 drives may be used for a centralized syslog project.)

Then we'll put the 880 in single user mode, fsck /opt, ufsdump /opt to its new
home, modify /etc/vfstab, fsck the new /opt to verify, and boot. We'll probably
also add a few metadb copies to the 3 drives since the only metadb's are on
disks 0 and 1 now.

QUESTIONS:

What steps are we overlooking?
Are there any problems with putting /opt on a RAID-5 SVM metadevice?
I really should wait 'til Monday shouldn't I?

Thanks!
-John
