I am learning Linux...have some Solaris experience tho
I suspect you will not have the device drivers to mount the SAS drives.
In Solaris we use the devfsadm "device filesystem administration?" command to "re-discover" hardware.
After this command a format usually discovers the "new" disks.
What do you use in Linux?
I am NOT an expert on Live Disks, but it seems that they will not have the drivers you need for anything "off-piste". Anyone please correct me?
