How to find missing disks on Sun x4150 without reboot?

Hi, Here is the issue: There are 4 disks on this Sun x4150 system under Solaris 10, but only 1 disk can be seen by the OS. I've tried commands disks and devfsadm but not working. It's an important production server, so 'reboot -r' is not a choice.

Thank you in advance!

Im pretty sure the X4150's have internal raid controllers. If you do and you are using it, you have to go into that at boot and add the volumes.

I think you are right. That's also my study result. If these disks were not configured at BIOS level, they won't be recognized by the OS.

That's a big issue. We have to make a down time to reconfigure the disks at BIOS level.

Is there a better solution?

what is the output of:

# raidctl -l c0t0d0

?

edit:
the above won't work... it's the STK raid controller... but, you can use the software from intel to manage the raid-controller from os level

Thanks a lot, DukeNuke2. The info you provided is very helpful. I am working on it now.

Individual disks are not seen in the O/S if RAID is configured on the LSI controllers (just the volume name) but disks can be not seen at all in the O/S with Adaptec (Sun STK) controllers without first initializing them.
The Adaptec based cards require all disks to be initialized first in the BIOS level setup utility before the O/S is given a device path to them.
This is the same for all operating systems installed.

So, checkout the result of the following Solaris command:

/opt/StorMan/arcconf GETCONFIG 1

You may see all the disks you have installed in a pre-configured RAID volume.

If you just see the one disk then reboot, and in BIOS select <CTRL><A> when prompted.
Then initialize the remaining disks detected in the BIOS setup utility that presents itself after <CTRL><A> is pressed.

The BIOS output will look something like this so press <CTRL><A> when you see this:

You iostat output shows it's an Adaptec (STK) card pre-configured with a RAID volume:

Vendor: Sun Product: STK RAID INT Revision: V1.0 Serial No: Size: 293.39GB <293391564288 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 2 Predictive Failure Analysis: 0
If RAID was not configured, the details in the "Product:" field would be the drive vendor like Seagate, not the string "STK RAID INT"

So, the following command will indeed tell you all about your Adaptec (STK) RAID configuraiton:

/opt/StorMan/arcconf GETCONFIG 1

Hope this helps,

I installed the StorageTek Raid Manager called arcconf that can see all the physical disks.

Thanks!
