- Login to the server by SSH or console and run the following command
# lspci | grep SAS
02:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] (rev 03)
The ouput shows the model of RAID which on this case is LSI SAS2008. As far as internal servers are concerned the M600 and M605 use SAS1068E which is SAS standard. C6100 servers use SAS2008 which is SAS2 standard. - For SAS1068E we use a utility called “lsiutil” . It can be downloaded from here:
For Xen server we use the 32 bit version called “lsiutil” and for PSBM we use the 64 bit version called “lsiutil.x86_64”
Assuming that is downloaded to /root folder.# chmod a+x lsiutil or chmod 755 lsiutil
- Run the utility by following command
# ./lsiutil or ./lsiutil.x86_64

- When propmted with “RAID actions menu, select an option: [1-99 or e/p/w or 0 to quit] ”
select 1 to show the status of volume and select 2 to view the status of physical disks. If you select 2 the output is like the following:1 volume is active, 2 physical disks are active
PhysDisk 0 is Bus 0 Target 1

- For SAS2008 we use sas2ircu utility. After downloading and extracting proper version
# chmod a+x sas2ircu or chmod 755 sas2ircu
- First we obtain the list of RAID controllers by running the following command:
# ./sas2ircu list
