In this example, replace the Fibre Channel switch connected to the HBA with host
port number
0001
.
3. Place in Online status the path that goes through the replaced Fibre Channel
switch.
For example, to place in Online status the path that goes through the HBA with
host port number
0001
and bus number
0000
, execute the following command:
# /opt/DynamicLinkManager/bin/dlnkmgr online -hba 0001.0000
4. Check the path information.
For example, execute the following command:
# /opt/DynamicLinkManager/bin/dlnkmgr view -path
For details about the path information, see 6.7 view (Displays Information).
4.6.4 Changing the HDLM Device Configuration
This section describes the actions and procedures to change the HDLM device
configuration.
To set up or change (add, change or delete) an LU in a storage system, use the
management program of the storage system, rather than the HDLM functionality. For
more information on configuring or changing an LU, see the manual provided with the
storage system.
All the actions performed via the HDLM-configuration definition utility (
dlmcfgmgr
)
are logged in the
/var/opt/DynamicLinkManager/log/dlmcfgmgr1.log
file.
By looking in this file, you can examine the change(s) made to the configuration, or
the reason why the execution of the
dlmcfgmgr
utility failed. For more information
on the
dlmcfgmgr
utility log, see also 2.11.1 Types of Collected Logs. For more
information on the
dlmcfgmgr
utility, see 7.3 dlmcfgmgr Utility for Managing the
HDLM Configuration.
(1) Notes on Changing the HDLM Device Configuration
Note the following when changing the HDLM device configuration:
„ When an HDLM device is excluded from HDLM management, the
AutoPATH_ID
s assigned to the paths for that device will be released. Because of
this, after paths for an HDLM device are released, the
AutoPATH_ID
s of the
paths may be displayed in a non-consecutive sequence.
„ When an HDLM device is included in HDLM management, HDLM assigns an
AutoPATH_ID
in sequential order (from the lowest available number) to the path
of that HDLM device.
„ When an HDLM device that is not managed by HDLM is included in HDLM
