HP XP Racks - Manual (Page 231)

Specify the current AutoPATH_ID of the target path, which is displayed by
using the view operation. For details about the view operation, see view
(Displays Information) on page 6-34 . Leading zeros can be omitted
(000001 and 1 indicate the same AutoPATH_ID); however, when the
target AutoPATH_ID is 000000, enter 000000 or 0 for the parameter
value.
AutoPATH_IDs are re-assigned every time the host is restarted. When you
want to add a new LU without restarting the host, AutoPATH_IDs are re-
assigned to each path of the LU when you execute the cfgmgr command.
Always make sure that you use the view operation to find the current
AutoPATH_ID of the target path, before executing the online operation.
-hdev host-device-name [-ospathid OS-management-path-ID]
Use this parameter to place online path connected to the specified host
device. If the -ospathid parameter is not specified, path with the
specified host device name are placed online.
For host-device-name, specify the value of HDevName.
For OS-management-path-ID, specify the value of OSPathID. Leading
zeroes can be omitted from the OS management path ID (00001 and 1
are the same value).
To display HDevName and OSPathID, execute the view operation as
follows:
# /usr/DynamicLinkManager/bin/dlnkmgr view -lu
For details on how to execute the view operation and display the host
device name and OS management path ID, see To Display LU Information
on page 6-57 in Parameters on page 6-36 . Only one set of values can
be specified for the -hdev parameter. This parameter is not case
sensitive.
Example
The following shows an example of placing online path for which the
host device name is hdisk0 and OS management path ID is 00001
while confirming command operation.
# /usr/DynamicLinkManager/bin/dlnkmgr online -path -hdev
hdisk0 -ospathid 1
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.
