4.1.9 Notes on Replicating a System
You can use the OS's
mksysb
command to back up hosts that include HDLM-managed
devices. If you then replicate (clone) a system from a mksysb image created in this
manner onto another LPAR or host, you must update the HDLM information to match
that of the destination system's environment.
To update the HDLM information to match that of the destination system's
environment, use the following procedure to execute the HDLM restoration support
utility (
dlmpostrestore
) after you have restored the mksysb image.
To update HDLM information:
1.
After restoring the image, log in to the activated host as a user with root
permissions.
2. Execute the
dlmpostrestore
utility.
# /usr/DynamicLinkManager/bin/dlmpostrestore
A message for confirming whether to continue processing is displayed
(
KAPL10552-I
is displayed in a local boot disk environment, and
KAPL10555-I
is displayed in a boot disk environment). To continue processing, enter
y
in
response to this message.
If you executed the utility in a boot disk environment, you must then restart the
host.
For details about the
dlmpostrestore
utility, see 7.8 dlmpostrestore Utility for
HDLM Restoration Support.
