"quite a bit of experience with Solaris" is probably a big overstatement. I have done system administration only out of necessity for the past 20 years on various *nix systems. So I have experience over many years, but it is infrequent experience. The main sysadmin around here has not dealt with Solaris for years. So while I remember a few things, google is my friend.

Running StorMan, I see the claim that the raid controller is "Sun STK RAID INT", but that's about all the info I seem to be able find without rebooting - which I guess I will be doing soon. My main worry right now is that if I swap out a disk (a single-volume disk, not one from the RAID) that the controller may lose knowledge of it. However, I have THAT data backed up, so it's not a big deal if I lose it. And I guess if I can actually mount and read the old system disk in the freed up slot, I should be able to repeat that process when I put back whatever disk I pulled out to make room.

I've already run fsck -y a number of times on the bad disk, so whatever damage that may have done is already done.

I know what to do in general, but I am trying to avoid a misstep that will damage the disk further and prevent me from getting as much info as I can off of it.

Thanks.

NAME

       chs - IBM ServeRAID PCI host adapter driver

DESCRIPTION

       The chs driver is the IBM ServeRAID PCI controller driver.

PRECONFIGURATION

   Known Problems and Limitations
       To  prevent  data  loss,  a  SCSI disk drive that is not defined as part of any physical pack within a logical drive will not be accessible
       through the Solaris operating environment.

CONFIGURATION

       Auto-configuration code determines whether the adapter is present at the configured address and what types of devices are attached  to  it.
       The IBM ServeRAID is primarily used as a disk array (system drive) controller.

       To  configure the attached disk arrays, you must configure the controller (using the configuration utilities provided by the hardware manu-
       facturer) before booting the Solaris operating environment You use the configuration utilities to set RAID levels, stripe parameters, cache
       mechanisms and perform other functions. For more information, see the user manual supplied with your hardware.
