Chapter 8 Disk Array Configuration Setting (S100/S1100/S1200/S1300/S2100/S2200/S2300)
IV-126
(F) Setting LD
Specifies the number of LDs to bind or their capacity (or both).
• Only specify the number of LDs
The maximum capacity that can be created is automatically calculated for the individual LD Capacity. Since,
in this case, the number of LDs to bind in a RANK is specified, the number of actually bound LDs is the
specified value multiplied by the RANK count.
• Only specify LD capacity
The maximum number that can be created is automatically calculated for the number of LDs to be bound in the
RANK. Information such as the number of LDs that are finally bound and their capacity can be checked with
8.2.4 (6) “Confirm LD Batch Binding screen” after clicking the [OK] button.
• Specify both the number of LDs and LD capacity
Any value can be set to the number of logical disks/capacity. The acceptability of the set value is verified after
the [OK] button is clicked. If the set value is in error, an error message is output.
1. The capacity which is entered into the input field can be used by the user. However, depending on the input
value and the RAID configuration, a capacity exceeding this value may be obtained. The reason is that, since
the minimum unit that can be bound in the case of RAID5(n+P) is 128KBxn, disks are bound in terms of
rounded-up MBs if the resulting figure cannot be divided. As the area for use in the RANK, there is not only
the capacity for use by the user but also the disk management area.
2. The maximum number of LDs which can be bound in the same RANK is 36.
(G) Setting LD Type/Name
For the LDs to bind, it is possible to set their formats and names simultaneously with their binding. The LD
name needs to be unique in the system (no two names must not be the same). Therefore, when binding multiple
LDs, the LD names in which the sequential numbers are added to the specified character strings are automatically
given.
The value initially displayed in the LD name input field is 20 characters which result from adding 4 characters of
the logical disk number to 16 characters inherent to the disk array. When the logical disk name is not changed,
the above-mentioned initial value is set.
When the LD type is not changed, the LD Type is made blank.
Example: 0200200000004C518CAC0000, 200000004C518CAC0001, …
Moreover, when the LD Type is made blank, the value set before shipment is initially displayed. The LD Type
is made blank, and “16 characters inherent to the disk array + 4 characters of the logical disk number” is set for
