HP Hitachi Dynamic Link Manager Software - Manual (Page 407)

The following shows an example of how to place online a path whose
SCSI device name is /dev/sde while confirming command operation.
# /opt/DynamicLinkManager/bin/dlnkmgr online -path -device /
dev/sde
KAPL01050-I The currently selected paths will be changed to
the Online status. Is this OK? [y/n]:y
KAPL01061-I 1 path(s) were successfully placed Online; 0
path(s) were not. Operation name = online
-hapath
Use this parameter to change to the Online status when the paths to the
primary volume (P-VOL) in an HAM environment are in the Online(S) or
Online(D) status. 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 in the Online(S) and Online(D) statuses, specify only -
hapath.
-dfha
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) do
not occur 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.
-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:
# /opt/DynamicLinkManager/bin/dlnkmgr online -pathid 2 -s
KAPL01061-I 1 path(s) were successfully placed Online; 0
path(s) were not. Operation name = online
