„
For a 2.4 series kernel
Check /proc/dualpath/ddX (where X is a, b, c … as many as number of logical disks
assigned to server).
If the “
partition-info
” field is “NML”, the paths have been multiplexed normally.
* If nothing is displayed, the logical disks in RAID Storage that are assigned to the server
are not being recognized on any access path. 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
