During the installation of the HCP software, you need to specify the type of storage the system uses. The options are internal and external.
For RAIN systems, you need to specify that it’s internal. For SAIN systems, including those that use internal storage in addition to the SAN storage, you need to specify that the storage is external.
Additionally, for SAIN systems, you need to know:
- Whether any of the storage arrays used by the HCP system are shared with other applications or systems
- Whether the HCP nodes are blades in one or more Hitachi CB 320 servers and, if so, the IP address of the management module (also called the chassis IP address) for each server
If the HCP system is using CB 320 servers, for each CB 320 server, you need to add the lowest-numbered storage node in the HCP system to the list of SNMP managers in the server configuration. For the community name, use public. To identify the node, use its front-end network IP address. If the node has multiple front-end network IP addresses, you need to create a separate SNMP manager list entry for each front-end network IP address.
If the lowest-numbered node changes at any time (for example, due to prolonged node unavailability or the addition of a node with a lower number), you need to update the configuration of each CB 320 server accordingly.
For information about configuring CB 320 servers, see the applicable Hitachi documentation.
- From your SAN administrator:
- Whether any nodes in the HCP system have index-only volumes (that is, logical volumes with numbers in the range 64 through 91) and, if so, the intended configuration of those volumes.
- Whether any nodes in the HCP system have spindown volumes (that is, volumes with numbers in the range 96 through 127) and, if so, the intended configuration of those volumes.
- If any nodes have spindown volumes, the controller 0 (zero) and controller 1 (one) IP addresses for each array on which those volumes reside. To verify that you’ve entered these addresses correctly during the HCP installation setup, you should also know the serial number of each array.
