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
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
smartctl version 5.38 [x86_64-redhat-linux-gnu] Copyright (C) 2002-8 Bruce Allen

Smartctl open device: /dev/sda failed: No such file or directory
V9600_1 (CBS): ~# smartctl -d scsi -a /dev/sdb

The smartctl utility on the APMs doesn't have the ability to access the LSI SAS controller on APM-9600.
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.
V9600_1 (CBS): ~# sas2ircu 0 DISPLAY
