The dlmprsvkey Utility for Registering an HDLM Persistent
Reservation Key
This utility registers and displays a PRSV key on an HDLM host. A PRSV key is
required to operate HDLM functions. This utility is executed automatically
during an installation of HDLM. A registered PRSV key becomes valid after the
host is rebooted. This utility is located in the following location:
HDLM-installation-folder\bin
Format
dlmprsvkey {-r [PRSV-key-to-be-specified-by-user][-s]| -v | -h}
Parameter
-r [PRSV-key-to-be-specified-by-user][-s]
Specify this parameter when you register a PRSV key.
PRSV-key-to-be-specified-by-user
A maximum of 16 hexadecimal digits can be specified.
• If this parameter is omitted, or the dlmprsvkey utility is
automatically executed during HDLM installation:
The dlmprsvkey utility for registering an HDLM persistent
reservation key creates a PRSV key by using the MAC address of
the NIC and the execution time of the utility. If the MAC address
of the NIC cannot be obtained, the dlmprsvkey utility creates a
PRSV key by using the execution time of the utility only.
• If this parameter is specified:
If less than 16 digits are specified, zeros will be added to the left
of the entered value to make it 16 digits. The specified value must
satisfy both of the following conditions:
- Must be a unique value among all the hosts in the SAN.
- Specifiable values are single-byte characters from 0 to 9, a to f,
and A to F. Values cannot be specified using zeroes only.
Example
In the following example, the utility registers the PRSV key without
specifying it on the host:
>dlmprsvkey -r
KAPL12104-I The operation for PRSV key registration will now
start. Is this OK? [y/n]: y
