E.3 Checking Connection from Application Server
This section describes how to check connection in Linux environment and check the PathManager
settings and status.
E.3.1 Confirmation Steps in Linux environment
After checking the FC cable connection between the application server and disk array unit, restart the
application server and run the following command to check the number of logical disks ("No. of logical
disks assigned to application server" × “No. of access paths from application server to individual logical
disks”) and the respective vendor and model names (NEC, DISK ARRAY).
Display example: When two logical disks are assigned to a server, with two access paths per logical
disk.
If nothing is shown, the OS was unable to recognize logical disks in the disk array
assigned to an application server. Check the connection between the server and disk
array unit, the Access Control host bus adapter driver settings, etc.
