The number that follows a
WWPN
keyword is the port WWN information of an
HBA.
The following steps assume that the HBAs whose WWN information is
underlined above are to be replaced.
2. Execute the
view
operation of the
dlnkmgr
command (
dlnkmgr view -path
-hbaportwwn
) to check the information about the paths that pass through the
HBAs you want to replace.
See the port WWN information of the HBAs you checked in step 1 and
HBAPortWWN
displayed as the execution result to check the host port number and
the bus number displayed in
PathName
.
In
PathName
, the leftmost number is the host port number. The number between
the period to the right of the host port number and the next period is the bus
number.
Specify the host port number and the bus number when you place the path in the
Offline(C)
status in step 3.
In this execution example, the host port number and the bus number
corresponding to the port WWN information of the HBAs to be replaced (the
underlined section) are shaded.
