Usually, raidctl command is used for a built-in raid1 controller, ie, mirroring one spindle to another (only). To configure an array normally needs an add-in card (third-party manufacture) with it's own software. Yes, it is possible that the drives you can't see are all connected to an add-in controller and I guess you'll only see that by taking the lid off the box. For instance, an add-in card could support a raid5 disk array which would disguise all the drives and make them look like something else to the Sun box. If you do take the lid off and find a card, make sure you get the make and model of the card whilst you are in there. You'll probably need to search for the management software.
There's an amber LED that is lit up on the system, so I logged on to take a look at the fault. I'm not sure how to interpret fault messages, and this one seems especially unhelpful:
Code:
-> start /SP/faultmgmt/shell
Are you sure you want to start /SP/faultmgmt/shell (y/n)? y

Fault class : fault.component.missing
FRU : /SYS
(Part Number: unknown)
(Serial Number: unknown)
Description : A required device is missing from the chassis.
Response : The service required LED on the chassis may be illuminated.
Impact : The services provided by the components will not be
available. The Host may not be permitted to power on.
Action : The administrator should review the ILOM event log for
additional information pertaining to this diagnosis. Please
refer to the Details section of the Knowledge Article for
additional information.

Try using:
Code:
format -e
from Solaris (#). Get into the scsi menu. Nothing to lose if you don't need the data on the disks.
Okay, I will try that. What should I do once I get into the scsi menu?

Yes, this is not looking good. I shut down the system and reseated all of the disks before running probe-scsi-all, and all of the drives are showing green lights (except for one, but after pulling it out and reseating it, the green light turned on).
It's an add-in card. That's why you can't see the drives.

This probably means that the two drives you can see are in a mirrored pair and the others are unallocated (and not published to the host at all).

Whenever this was delivered to your site there should have been manuals and software with it. Can you go find them??

Let me put it this way; between the disks and the Sun box there's a BIG chunk of electronics which is deciding how things are configured and what the Sun box sees and does not see.

What's likely here is that the drives (you can't see) were configured as a raid0 array (that's striping with no resilience) and when one drive went off-line (the one without the green light) the card took the array offline.
It is possible that if you shutdown (volts completely off) and cold boot (with the failed drive re-seated) it may recover. Alternatively, LSI software often includes an option to "mark the drive online". If you can do that to the failed drive it may recover. Otherwise, use the LSI software to configure a new array (raid0, raid3 raid5 or raid10) and publish a LUN to the host box.
Hope that helps.

Another thought is; you are showing 2 x 298GB drives. It is possible that you have two 298GB arrays configured. If they were raid5 then it could withstand one drive going offline. You might have 8 x 60GB or 8 x 80GB drives configured as two arrays of 4 drives. Have you tried creating some disk traffic on each "drive" and see which drive lights flash??

Thank you very much for the help. I opened up the lid and found the RAID controller connected to the RISER, which I think is causing the fault in the ILOM.
I am going to try to download the controller utility and figure out how I can get some information from it regarding the current configuration. Hopefully I can find the manuals for this but I have a feeling we don't have them. I will report back with my findings. Thanks again!
It's quite likely that everything is working normally. If you have 8 x 100GB drives configured as two RAID5 arrays, each array would lose the capacity of one drive (for parity) leaving a usable capacity of 300GB.
I have an Oracle VM set up with 1 virtual disk. I am trying to add 2 new disks to it. I was able to successfully add 1 (it appears when I run "format" in the VM) but when I add the second and third disks they do not appear in my VM.
