One of the two internal disks in a 280R running Solaris 9 has failed
and gone offline. I need to remove and replace it without shutting
the machine down. When I use `luxadm remove_device -F
/dev/rdsk/c1t0d0s2' to remove it, and give it `c' to continue, luxadm
generates lots of errors and terminates without giving me the prompt
to remove the disk. It apparently is unable to stop the bad disk.

Can I just remove the disk now without causing further harm?

How do I clean up the system so that I can insert a good disk in the
same slot? Will `devfsadm -C -c disk' do that?

I know how to proceed after that.

Almost but not quite. It depends what you are runnning.

There are a number of docs about disk replacement on Sunsolve
for various combinations of platform, scsi/fc-al, OS and volume
managers, including what to do when luxadm remove_device fails
(eg doc id 80445)

<rant> and Sun really ought to look at making this painless: give us
hardware raid controllers and let the software handle the details;
hell, easier device mapping to help us find the disks would be a start </rant>.

Thanks. I looked at a bunch of those documents, but must have
missed that one.
