A Hitachi Block Host node represents a group of Hitachi Block volumes attached to a host machine.
Note: A physical Block Device node must be created
using the Hitachi Block Device Node Wizard before any Block Host nodes can be created on it.
Note: A Block Host node can also be based off of a Logical Block Device, this must also have
been created before setting up the Block Host node using the Hitachi Logical Block Device Node Wizard.
If a user is given access to a Block Host node by placing it in a resource group that they have access to, the associated physical Block Device node must also be placed in that resource group. It is not sufficient to include only a Logical Block Device node (based on the physical Block Device node) in that resource group.

|---|---|
| Included Logical Devices | Enter a list of LDEVs or Host Groups to be included in this Block Host (one logical device or host group specification per line) in the format described below. |
| Excluded Logical Devices | Enter a list of LDEVs or Host Groups to be excluded from this Block Host (one logical device or host group specification per line) in the format described below. Tip: This enables the inclusion of an entire Host Group but exclusion of individual LDEVs within that Host Group.

LDEVS are entered using the format:
identifier
Where identifier is one of:
- ldev_id a single LDEV ID in hex or decimal
- ldev_id-ldev_id a range of LDEV IDs
- host_group_id a host group identifier using the format:
- CLc-s-h where:
- CL is a literal string
- c is the physical channel number in the range 1…n
- s is the physical slot number in the range A…Z
- h is the logical host group ID in the range 0…255
- CLc-s-h where:
For example:
0x00a0 for an LDEV specified in hexadecimal
220-230 for a range of LDEVs specified in decimal
CL2-A-12 for a host group
Note:
- Spaces and colons must not be present in the entries. If a space or colon is encountered on a line, the remaining text on that line from the space or colon will be disregarded. This allows entries that contain the LDEV name after a space or colon) to be present in the list.
