HP XP P9500 Storage - Manual (Page 41)

Keep in mind the following points:
•
The external volume is configured as follows:
0001 is configured as a LUN discovered through the primary path. ◦
◦ 1 is used for a path group number.
◦ E16384-4095 is configured for an external volume group (ExG).
•
Two cross-storage system paths are configured as follows:
The primary path
Port number on the local storage system: 1A
◦
WWN on the external storage system: 60060E8004F81370
◦ The alternate path
Port number on the local storage system: 1B
WWN on the external storage system: 60060E8004F81371
•
Attributes of the external volume are configured as follows:
Emulation type: OPEN-V ◦
◦ Cache mode: Enable
◦ Inflow control: Disable
◦ CLPR: 00
•
LDEVs are configured as follows:
Number of LDEVs: 3 ◦
◦ LDEV number: 00:00:00, 00:01:00, 00:02:00
◦ LDEV capacity: 96,000 blocks
Specifying LDEV Capacity
following processes to specify LDEV capacity for OPEN-V emulation types and non-OPEN-V emulation
types.
To specify OPEN-V emulation types:
•
Limits: 96000 to 8589934592
•
Create an LDEV at the beginning of a slot. If you specify the LDEV capacity indivisible by the
slot size (512 blocks), an adjustment area is created between the end of the LDEV and the
beginning of the next LDEV. You cannot use the adjustment area as an LDEV.
Calculate the adjustment area using the following equation:
Adjustment area capacity = ceiling[LDEV capacity ч 512] Ч 512 – LDEV
capacity
In the equation, ceiling indicates that the value that is enclosed in brackets must be rounded
up to the nearest whole number.
•
The capacity of the external volume must be greater than or equal to the sum of the total
capacity of all the LDEVs in the external volume plus the total capacity of the adjustment areas.
The following figure shows four LDEVs of 100,000 blocks each. The required capacity of the
external volume is 401,056 blocks.
