HP XP Racks - Manual (Page 232)

Use this parameter to change the paths to the primary volume (P-VOL) in
an HAM environment to Online(D). The Online(S) status changes to the
Online(D) status. When you do not specify this parameter, the status of
the P-VOL paths in the HAM environment will be changed to the
Online(S) status. If I/O operations to the secondary volume (S-VOL)
have never occurred and only the paths to the P-VOL recover from an
error, the path to the P-VOL will be in the Online status regardless of this
parameter specification. To change the status of a specific LU, use the -
lu and -pathid parameters to specify the path to the LU. To change the
status of all the paths, specify only -dfha. A regular online operation is
executed on the paths other than the P-VOL in an HAM environment.
If you use the -dfha parameter for a volume whose paths are all in the
offline status, the processing to the P-VOL paths might output a
KAPL01036-E message and fail even if the paths recover from an error. If
the paths indicated in the KAPL01036-E message are in the Online(S)
status and the paths to the S-VOL are in the Online status, re-execute the
command with the -dfha parameter specified.
-lu -pathid AutoPATH_ID
Specify management-target paths for each LU (P-VOL). The target LUs
are the LUs that belong to a path ID that you specify in the -pathid
AutoPATH_ID parameter.
-s
Executes the command without displaying the message asking for
confirmation of command execution from the user. Specify this parameter
if you want to skip the response to the confirmation message: for
example, when you want to execute the command in a shell script or
batch file.
Example
The following example shows how to place a path, whose
AutoPATH_ID is 000002, online without asking for confirmation of
command execution from the user:
# /usr/DynamicLinkManager/bin/dlnkmgr online -pathid 2 -s
KAPL01061-I 1 path(s) were successfully placed Online; 0
path(s) were not. Operation name = online
#
To Display the Format of the Online Operation
-help
Displays the format of the online operation.
Example
The following example shows how to display the format of the online
operation:
# /usr/DynamicLinkManager/bin/dlnkmgr online -help
