Issue/Introduction

How to check the health of RAID and individual hard drives on APM-9600If a VAP group is configured to use RAID on APM-9600, the traditional 'smartctl' command doesn't work:

CBS# show running-config vap-group V9600
vap-group V9600 xslinux_v5_64
raid 1
max-load-count 1
ap-list ap9
load-balance-vap-list 1 2 3 4 5 6 7 8 9 10
ip-flow-rule lb
action load-balance
activate

CBS# show ap-vap-mapping

Module Slot Status VAP IP Address VAP Group Index Master (true/false)

AP3 5 Active 1.1.21.102 fw 2 false

AP5 7 Active 1.1.21.101 fw 1 true

AP6 8 Active 1.1.21.105 V8650 1 true

AP9 11 Active 1.1.21.106 V9600 1 true

(4 rows)

CBS# show module status ap9 disk

Slot 11:
Board Type                   AP9600
Hard Disk                    450(GB)
Second Hard Disk             450(GB)
Hard Drive Error             None
Second Hard Drive Error      None
RAID Status                  Active, RAID 1

CBS# unix su
[[email protected] admin]# rsh V9600_1

V9600_1 (CBS): ~# smartctl -d scsi -a /dev/sda

V9600_1 (CBS): ~# smartctl -d scsi -a /dev/sdb

Cause

The smartctl utility on the APMs doesn't have the ability to access the LSI SAS controller on APM-9600.

Resolution

The verify the health of RAID and hard disks on APM-9600, the utility 'sas2ircu' can be used.

Linux command 'sas2ircu 0 DISPLAY' shows the healthy of the RAID and individual HDDs. In the below sample output, 'Status of volume: Okay (OKY)' and 'Status: Optimal (OPT)' show the RAID and the HDDs are healthy.
