Fixing inode error on mirrored Root disks.

I'm fairly new to Solaris administration... (Retread IBM Mainframe sysprog)

We have observed the following error message on one of our V1280 servers
that has a mirrored Root partition. This server is running Solaris 9,
using Solaris Volume Manager for mirroring.

[ID 879645 kern.notice] NOTICE: /: unexpected free inode 427288, run fsck
(1M) -o f

The gentleman that set this server up (top notch sysadmin) went on to a
better opportunity, so I am learning fast. Looks like the following
sequence of steps would get me through a correction... I would appreciate
any critiquing, or pointers, from more experienced folks. Thanks in
advance - I will summarize in return.

1.) Bring down server to OBP level
2.) Boot server off CDROM, single user mode (installation CDROM #1 ?)
3.) Mount root partition "/dev/dsk/c1t0d0s0" on " /a " (1st submirror)
4.) Run fsck on " /a "
5.) umount " /a "
6.) Repeat process for second submirror.
7.) Reboot back into multi-user mode.

Again, thanks for any advice that might be offered.
