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

ODM in order to check the
