13.2 Connection
Confirmation in a Linux Environment
(1) Confirmation procedure from Linux OS
After confirming that an FC cable is connected between the server and RAID Storage, restart the
server and execute the command below to check the number of logical disks (as many as the
number of logical disks assigned to the server times the number of access paths from the server
to each logical disk are displayed) and the vendor and model (RAID, RAID Storage 1000) of
each.
* If none are displayed, the logical disks in RAID Storage that are assigned to the server are not
being recognized by the OS. Check connections between the server and RAID Storage,
AccessControl settings, and the host bus adapter driver setup.
[Sample display]
When two logical disks are assigned to the server and there are two access paths for each
logical disk
