Solution 1018162.1 : How to Identify Disk Drives for Replacement in the Sun Storage D1000 Array

Applies to:

Sun Storage D1000 Array - Version All Versions and later
All Platforms

Goal

This article provides a method to identify the correct disk drive to replace in a D1000.

Solution

From the system console, first follow the procedures for removal of the failing drive if volume management software such as Veritas Volume Manager or Solaris Volume Manager is in use.
From the host system verify the failing drive by using the iostat command, or look at the error messages in /var/adm/messages to gather the drive serial number. Page through the output looking for hard errors on the disk devices. Once you identify the drive, make a note of the drive serial number from the iostat -E output. In the output below, sd8 is an instance number. and the corresponding c-t-d- device name is found in /etc/path_to_inst.

# iostat -E| more
. . . .
sd8 Soft Errors: 7 Hard Errors: 25 Transport Errors: 5
Model: ST318305LC Revision: 3.21 Serial No: 00391H8227
Size: 18.2GB
Next run the format utility.
Select the disk that is on the same controller but one target above or below the disk needing replacement or the closest disk available on the same controller. For instance, if c2t4d0 is the disk needing replacement, select c2t3d0 or c2t5d0.
Select the analyze/read option. This will inform you that it will take a while but will not harm data or OS and can be stopped by typing Ctrl-C.
Begin the analyze/read and allow it to run. This will flash the green access light on the D1000 for the disk you chose in a constant pattern, enabling you to identify the disk you need to replace. The disk to be replaced would be either before or after the "green access lighted" disk.
As an additional identifier, confirm that the serial number from the iostat -E output or /var/adm/messages can be verified on the disk itself.
Stop the analyze/read by typing Ctrl-C. Replace the failing disk and ensure the new disk spins up and the disk bay lights up solid.
Complete any volume management software procedures to begin the resyncing process.
