3. Creating an HDLM Environment

1. Log in to AIX as the root user.

If you are using a virtual I/O server, see the virtual I/O server documentation to

2. If there is no directory for mounting the DVD-ROM, make the directory.

# mkdir /

cdrom

cdrom is the desired directory name. Hereafter, cdrom is used for purposes of

explanation.

3. Mount the DVD-ROM.

# mount -r -v cdrfs /dev/cd0 /

cdrom

The /dev/cd0 part depends on the system.

4. Execute the following command to check that the devices to be managed by

HDLM have been recognized by the system:

# lsdev -Cc disk

hdisk0 Available 1S-08-00-8,0 16 Bit LVD SCSI Disk Drive

hdisk1 Available 1S-08-00-9,0 16 Bit LVD SCSI Disk Drive

hdisk2 Available 1S-08-00-10,0 16 Bit LVD SCSI Disk Drive

hdisk3 Available 1H-08-02 Hitachi Disk Array (Fibre)

hdisk4 Available 1H-08-02 Hitachi Disk Array (Fibre)

...

In this example, hdisk3 and hdisk4 are recognized as devices to be managed

by HDLM. If all devices to be managed by HDLM are recognized, proceed to step

If any devices to be managed by HDLM are not recognized, proceed to step 7.

5. Execute the following utility to remove, from the running kernel, the HDLM

management-target device:

# /cdrom/HDLM_AIX/hdlmtool/dlmrmdev -f

The KAPL10529-I message is displayed.

If the

KAPL10529-I message is not displayed, the HDLM management-target

device has not been deleted. Make sure that no processes, services, file systems,

or volume groups are using any HDLM management-target paths, and then

re-execute the above utility.
