HP StorageWorks Scalable File Share System Installation and Upgrade Guide Version 2.2

The configure array commandJ–6
Example 2:
The following example configures the arrays attached to the administration and MDS server (arrays 1 and
2 in this example) to support two file systems (one large file system and one smaller file system):
sfs> configure array 1,2 luns_size=33%,all
The command configures the arrays as follows:
• The administration LUN and the spare administration LUN are each 40GB in size (this is the default
size).
• A service LUN or spare service LUN for the server pair is automatically created on each array.
• The arrays are configured with two MDS LUNs in each disk group; one LUN uses 33% of the
available storage in the disk group (to support the smaller file system) and the second LUN uses all of
the remaining available storage in the disk group (to support the larger file system). The default is to
create one disk group on an array, therefore a total of two MDS LUNs are created on each array.
• ADG redundancy is used (by default), which allows eleven disks (the default) to be used in the disk
group.
Example 3:
The following example configures two arrays attached to a pair of Object Storage Servers (arrays 3 and 4
in this example) with one LUN in each disk group, which is the recommended configuration:
sfs> configure array 3,4
The command configures the arrays as follows:
• A service LUN or spare service LUN for the server pair is automatically created on each array.
• The arrays are configured with one OST LUN in each disk group; the default is to create one disk
group on an array, therefore one OST LUN is created on each array. This is the recommended
configuration.
• ADG redundancy is used (by default), which allows eleven disks (the default) to be used in the disk
group.
Example 4:
The following is an example of configuring an array where 500GB disks are used and the array is attached
to a pair of Object Storage Servers:
sfs> configure array 4 luns_size=2048,2048
The command configures the arrays as follows:
• A service LUN or spare service LUN for the server pair is automatically created on the array.
• The array is configured with two LUNs in each disk group; the default is to create one disk group on
an array, therefore a total of two OST LUNs are created on the array.
• ADG redundancy is used by default (also, ADG is the only RAID type supported for 500GB disks).
This allows eleven disks (the default) to be used in the disk group.
