Appendix E How to Set/Check Application Server (Linux) (FC/SAS)
2. Check the PathManager status
Check
/proc/scsi/sps/ddX
, where X is a, b, c, ... (number of logical disks assigned to server).
The
path-info:
line exists only for multiplexed sections of each device, and if NML appears in all of
the status columns of device-info:, paths are normally multiplexed.
Display example:
When two logical disks are assigned to a server, with two access paths per logical
disk.
3. Check the path patrol daemon
Confirm that the path patrol daemon is running.
When the path patrol daemon is started, the following message is displayed.
Display may vary slightly among different operating systems.
If nothing is shown, none of the access paths recognized the logical disks of the disk array
unit assigned to the application server. Check the connection between the application
server and the disk array unit, the Access Control settings, host bus adapter driver
settings, etc.
