If disk-led-assoc is not set up use the follwing procedure to find out where the disk is located in the front of the Enterprise 450.

Find the c#t#d# of the disk giving us problems by using the format command:

AVAILABLE DISK SELECTIONS:

0. c0t0d0 <SUN4.2G cyl 3880 alt 2 hd 16 sec 135>

/pci@1f,4000/scsi@3/sd@0,0

1. c0t1d0 <SUN4.2G cyl 3880 alt 2 hd 16 sec 135>

/pci@1f,4000/scsi@3/sd@1,0

2. c2t0d0 <SUN4.2G cyl 3879 alt 2 hd 16 sec 135> <------ We will use this disk as an example

/pci@6,4000/scsi@4/sd@0,0

3. c2t1d0 <SUN4.2G cyl 3879 alt 2 hd 16 sec 135>

/pci@6,4000/scsi@4/sd@1,0

From This serial number 9716E30027 write down the last 5 numbers in this case it is 30027

On every disk in a Enterprise 450 there is a number on the front bracket in this example it is 0020772-9716E30027

Notice that the last numbers match the serial number on the drive. Once you have a match you have found your disk!

___________________________________________________________________________________________

Notice: There are a few Seagate drives where the matching numbers are in the middle of the number given from iostat

Example:c0t3d0 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0

Vendor: SEAGATE Product: ST34371W SUN4.2G Revision: 7462 Serial No: JDE915350PJ46U

The numbers 91535 match the numbers on the drive bracket for this disk.

This procedure works for Solaris 2.6 and above

you can use this information in conjunction with infodoc #16735 to help set up disk-led-assoc
