3.5.6 Migrating from HDLM Version 5.8.1 or Earlier to Version 5.9 or
Later
When HDLM version 5.8.1 or earlier is migrated to HDLM version 5.9 or later, the
logical device file that can be controlled by the HDLM driver changes from the HDLM
device (
dlmfdrv
n) to hdisk. If the user application uses an LU managed by HDLM,
modify the user application appropriately.
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
