7.4 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
7.4.1 Format
dlmprsvkey {-r [PRSV-key-to-be-specified-by-user][-s]| -v | -h}
7.4.2 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
