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.

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


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

Disks Missing for Adaptec (STK) Controllers

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:

Adaptec RAID BIOS V5.3-0 [Build 16732]
(c) 1998-2008 Adaptec, Inc. All Rights Reserved
Press <Ctrl><A> for Adaptec RAID
Booting the Controller Kernel....Controller started
Controller #00: Sun STK RAID EXT at PCI Slot:02, Bus:04, Dev:00, Func:00
Waiting for Controller to Start....Controller started

Battery Backup Unit Present
Controller POST operation successful
Controller Memory Size: 256 MB
Controller Serial Number: SOMESERIALNUM

One or more drives are either missing or not responding.
Please check if the drives are connected and powered on.
Press <Enter> to accept the current configuration.
Press <Ctrl-A> to enter Adaptec RAID Configuration Utility.
Press <Ctrl-H> to Pause Configuration Messages.
(Default is not to accept if no valid key pressed in 30 second)
Timeout. BIOS took the default Configuration.

Location Model Rev# Speed Size

J2 : Dev 00 ATA SEAGATE ST32500N 3AZQ 3.0G 238.4 GB
J3 : Dev 00 ATA SEAGATE ST32500N 3AZQ 3.0G 238.4 GB

Hope this helps,

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.
