4. HDLM Operation
384
If the SCSI device of the new path that HDLM detected is not yet registered, a new
HDLM device is allocated to the path. For example, if you define a new path from the
host to an LU of the storage system, a new HDLM device is allocated to the path. The
lowest available alphabetical letter is allocated as the logical device file name of the
HDLM device.
Examples of the logical device file name of the HDLM device when a new HDLM
device is allocated are shown in Table 4-5: Example: Allocation of New HDLM
Devices.

If the error message
KAPL10357-E
is displayed, HDLM does not add an HDLM
device even though a new LU was recognized. In this case, you must execute the
HDLM-configuration definition utility (
dlmcfgmgr -u
) to delete the HDLM
device(s) not in use (or, represented with a hyphen (-)) to release the available name(s)
