HP XP P9500 Storage - Manual (Page 432)

Examples
Example 1: The -a option is specified:
Information on the newly added LUs is applied to the HDLM driver based
on the contents of the HDLM driver configuration definition file (/kernel/
drv/dlmfdrv.conf). In Solaris 10 or Solaris 11, information on the LUs
that were disconnected from the host is deleted from the HDLM driver. In
Solaris 8 or Solaris 9, information on LUs that are already managed by
HDLM is not updated.
# /opt/DynamicLinkManager/bin/dlmcfgmgr -a
Example 2: Options are omitted:
In this example, the dlmcfgmgr utility outputs an error message and
displays help about the usage of the command.
# /opt/DynamicLinkManager/bin/dlmcfgmgr
KAPL10380-E A parameter is invalid.
KAPL10368-I usage: dlmcfgmgr {-a | -h}
#
Note
¢
Execute the dlmsetconf utility for creating the HDLM driver
configuration definition file before executing the dlmcfgmgr utility.
¢
If you use VxVM, do not use the dlmcfgmgr utility. Instead, specify
the reconfiguration option, and then restart the host. To register the
HDLM device to VxVM or cancel the HDLM device registration from
VxVM, you need to restart with the reconfiguration option specified.
¢
The correspondence between the paths and path IDs might differ
depending on whether dynamic reconfiguration of the HDLM device is
performed by executing the dlmcfgmgr utility or by restarting the
host.
¢
You must restart the host after performing an upgrade installation or
re-installation. LUs will not be added or deleted dynamically if you
execute the dlmcfgmgr utility before restarting the host.
¢
If the HDLM driver configuration definition file (/kernel/drv/
dlmfdrv.conf) contains the definition of a newly added LU, the
dlmcfgmgr utility makes the HDLM driver recognize the new LU so
that the LU is to be managed by HDLM. If the definition of an existing
LU no longer exists in the HDLM driver configuration file
(dlmfdrv.conf file), the dlmcfgmgr utility deletes the existing LU
from the HDLM driver and excludes it from HDLM management.
¢
If an LU is deleted (in Solaris 8 or 9), a path is deleted for an LU, or a
path setting for an LU (for example, the instance number) is changed,
the configuration information used by the HDLM driver is not
dynamically updated. To update the configuration information in any
of these cases, specify the reconfiguration option and then restart the
host.
