Storage Module Disk Ready-to–Remove LED Does Not Work Using cfgadm (6946124) - Sun Blade Storage Module M2 Product Notes

Storage Module Disk Ready-to–Remove LED Does Not Work Using `cfgadm` (6946124)

The Ready–to–Remove LED to locate a drive does not work when using the cfgadm -c unconfigure command on Sun Blade T6320 or Sun Blade T6340 blade servers.

Workaround

Run the format command to select the device that you need to locate.

Example:

bash-3.00# format

Specify disk (enter its number): 4 
selecting c0t5000C5000258C457d0

Find the serial number for the device that you selected in Step 1.

Issue the command: iostat -En > iostat_output

Sselect the iostat_output file and search for "Cxtx...." number of the disk identified in step 1.

bash-3.00# cat iostat_output

Run the REM's sas2ircu utility to do the following:

Find the SAS2 controller number/index using sas2ircu LIST command.

bash-3.00# ./sas2ircu LIST

Find the drives connected to this controller using sas2ircu n display > sas2ircu_output.

Where n is the controller number from the Step 3a.
```
bash-3.00# ./sas2ircu 0 display > sas2ircu_output
```

Look for the serial number that matches the value in Step 2 from the sas2ircu_output file.

Once the serial number is identified, look for the enclosure/slot# that corresponds to this device.

If the enclosure ID# is 1, it indicates the drives are in a server blade. If Enclosure# is not 1, that indicates the drives are in a storage module.

The slot# refers to the disk slot number on the server blade or storage module.

Example for drives in a Sun Blade T6320 or T6340:

Note - In this example, the Enclosure and Slot numbers are 1, which means the drive is sitting in Slot#1 labeled as HDD1 on the server blade.

bash-3.00# cat sas2ircu_output

Device is a Hard disk
 Enclosure #                             : 1
 Slot #                                  : 1

For drives in a Sun Blade X6270 M2, an example would be:

bash-3.00# cat sas2ircu_output

Device is a Hard disk
 Enclosure #                             : 6
 Slot #                                  : 7

Locate the drive in storage module.

Once you identify the Enclosure# and Slot#, use LOCATE subcommand of sas2ircu. The locate ID on the drive will start blinking (amber). If you replace the drive with another drive, turn off the locate LED using LOCATE sub command of sas2ircu. For example:

bash-3.00# ./sas2ircu 0 LOCATE 6:7 ON

Version 3.250.02.00 (2009.09.29)

SAS2IRCU: LOCATE command completed successfully.
SAS2IRCU: Command LOCATE Completed Successfully.

Please turn off drive locate LED after replacing the drive using
following command:

bash-3.00# ./sas2ircu 0 LOCATE 6:7 OFF
