HP XP RAID Manager Software - Manual (Page 38)

Setting up UDP ports
This section contains information that may be of assistance in setting up strict firewalls.
If you do not have a HORCM_MON IP address in your configuration definition file, RAID Manager
(horcm) opens the following ports on horcmstart.
•
When either the in-band or out-of-band method is used:
[31000 + horcminstance + 1]
•
When the out-of-band method is used:
[34000 + horcminstance + 1]
If you have a HORCM_MON IP address in your configuration definition file, you need to open up
the port that is defined in this entry.
Setting the command device
For in-band RAID Manager operations, commands are issued to the RAID storage system via the
command device. The command device is a user-selected, dedicated logical volume on the storage
system that functions as the interface to the RAID Manager software on the UNIX/PC host. The
command device is dedicated to RAID Manager communications and cannot be used by any other
applications. The command device accepts read and write commands that are executed by the
storage system and returns read requests to the UNIX/PC host.
The command device can be any OPEN-V device that is accessible to the host. A LUSE volume
cannot be used as a command device. The command device uses 16 MB, and the remaining
volume space is reserved for RAID Manager and its utilities. A Virtual LUN volume as small as 36
MB can be used as a command device.
First you set the command device using LUN Manager, and then you define the command device
in the HORCM_CMD section of the configuration definition file for the RAID Manager instance on
the attached host. When you use a command for provisioning, user authentication is required. Set
enable the user authentication on the security attribute of a command device.
To set a command device:
1.
Make sure the device that will be set as a command device does not contain any user data.
Once a volume is set as a command device, it is inaccessible to the host.
2. Log on to Remote Web Console, and connect to the storage system on which you want to set
a command device.
3. Configure the device as needed before setting it as a command device. For example, use
Virtual LUN or Virtual LVI to create a device that has 36 MB of storage capacity. For
instructions, see the HP P9000 Provisioning for Open Systems User Guide.
4. Launch LUN Manager, locate and select the device, and set the device as a command device.
For more information, see the HP P9000 Provisioning for Open Systems User Guide. If you
want to use the RAID Manager Protection Facility, also enable command device security at
this time. For instructions, see the HP P9000 Provisioning for Open Systems User Guide. For
information about the Protection Facility, see the HP P9000 RAID Manager User Guide.
5. Write down the following information about this command device. You will need this
information when you define the command device in the configuration definition file.
