Notes
• When an LDEV is allocated to a path and then another LDEV is allocated
to the same path (host port number, bus number, target ID, and host LU
number), the HDLM device name for the new LDEV might sometimes be
the same as that for the old LDEV. For example, when an LDEV is
deallocated while a host is running, another LDEV can be allocated to the
same path. In this case, if an application preserves the settings to use
that HDLM device name, a program such as a higher-level program
product of HDLM accesses that HDLM device without recognizing that the
LDEV was changed. This might result in data corruption. Check that the
HDLM device name you previously used is nowhere to be found before
deallocating the LDEV.
• You cannot execute multiple instances of the dlmcfgmgr utility at the
same time.
• You cannot execute the dlmcfgmgr utility while the dlmstart utility is
executing.
• A logical device file name of the HDLM device file that can be specified
with the -i, -o, or -u parameter of the dlmcfgmgr utility can consist of up
to 4,095 characters. If a name is more than 4,096 characters long, the
error message KAPL10358-E is displayed.
