To migrate to HDLM version 5.9 or later:
1. Log in to AIX as a user with root permissions.
¢
If you are using a virtual I/O server, see the virtual I/O server
documentation for details about how to log in to AIX.
¢
If you are not using a virtual I/O server, proceed to step 10.
2. Check the virtual SCSI disk recognition method being used.
Execute the dlmodmset utility for setting the HDLM execution environment
ODM in order to check the unique_id value:
The following shows an example of executing this utility when HDLM 5.6.3
has been installed:
# dlmodmset -o
Inquiry Log : on
Inquiry Log File Size : 1000
hdisk error check flag : on
HDLM pbuf count : 16384
Lun Reset : off
unique_id : off
HDLM Subclass : node
KAPL10800-I The dlmodmset utility completed normally.
#
If the unique_id value is on, the unique_id method is being used. If it is
off, the PVID method is being used. If the unique_id method is being
used, proceed to step 8.
3. Execute the following command to activate the volume group that is using
the virtual SCSI disk of the HDLM management-target hdisk:
# varyonvg volume-group-name
4. Execute the following command to mount the file system (under control
of the volume group) in the client logical partition:
# mount file-system-mount-point
5. Execute the following command to back up the volume group in the client
logical partition:
# savevg -i -f any-file-name-or-device-volume-name volume-group-
name
6. Execute the following command to unmount the file system in the client
logical partition:
# umount file-system-mount-point
7. Execute the following command to delete the volume group in the client
logical partition:
# reducevg -df volume-group-name hdisk-name
8. Execute the following command to delete the virtual SCSI disk in the
client logical partition:
# rmdev -dl hdisk-name
