Solution 1012018.1 : How To replace an Internal disk on a Sun Fire[TM] V1280/E2900 & Netra[TM] 1280/1290

Applies to:

Sun Netra 1280 Server
Sun Fire V1280 Server
Sun Fire E2900 Server
Sun Netra 1290 Server - Version: Not Applicable and later [Release: N/A and later]
All Platforms

Goal

The following is the procedure to remove internal disks in the Sun Fire[TM] V1280/E2900 & Netra[TM] 1280/1290. It is not recommended to remove a disk if the power LED is on and the ok_to_remove LED is not ON.

Solution

When identifying a disk for replacement in a V1280/E2900 & Netra[TM] 1280/1290, the disk target to physical slot locations are as follows:

target 0 (cXt0dY) = the disk in the lower physical slot
target 1 (cXt1dY) = the disk in the upper physical slot

X = controller number
Y = disk number

Once disk is identified, you need to detach/unmount/unconfigure your disk/filesystems through the software you are using (for example, Solstice DiskSuite[TM]), otherwise you risk damaging them. The ok_to_remove LED should be lit, when the disk is unconfigured using cfgadm. Also, keep in mind that the power/active LED goes on when the disk is mounted, but only goes off if the power is removed in the IB_SSC. There are no individual switches in the power feeds to either of the disks.

The following is an example of how it should appear:
In this case we will remove disk1 (target 1),

# cfgadm -a

Note above that c1t1d0 is connected and configured.
Now check to see what is mounted on that drive.
Unmount anything mounted on that drive next.

#

Note above that c1t1d0 is now unconfigured. At this point the yellow light is on the 'ok-to-remove` LED. Now you can remove the disk.
Put the new drive in, the yellow LED will still be lit beside the drive.

Next, configure the new disk.

# cfgadm -c configure c1::dsk/c1t1d0

Check to see that it is configured.

# cfgadm -a
