4. HDLM Operation
196
# /usr/DynamicLinkManager/bin/dlnkmgr view -path
If you deleted all devices, check that the following message appears:
KAPL01019-W The target path was not found. Operation name =
view
If you deleted a specific device, check that the deleted device (hdisk name) is no
longer displayed.
(3) Changing an HDLM Management-Target Device
Note
If you execute the
chdev
command while a path is in error status, that path will
be deleted. In such a case, first recover from the path error, then re-execute the
cfgmgr
command, and finally perform the following steps:
1. Inactivate the volume group used by HDLM.
# varyoffvg
volume-group-name
2. Execute the
chdev
command to change attributes.
The following example changes the queue depth and timeout value:
# chdev -l
hdisk-name
-a queue_depth=8 -a rw_timeout=60
3. Inactivate the volume group used by HDLM.
# varyonvg
volume-group-name
4.5.2 Changing hdisk attributes
hdisk attributes consist of default values and values actually used. When a new hdisk
is configured, or deleted and then reconfigured, the actual value for hdisk attributes is
set using the default values.
The HDLM default settings modification utility (
dlmchpdattr
) can be used to
change the default values.
Note:
To change attribute values for an individual hdisk, use the
chdev
command
