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

Step 7: Configuring storage for the administration server 7–23
CAUTION: If you specify the luns_size option with the configure array
array_number command, use all of the available space in the disk group. If you do not, the
remaining space will not be usable, as you cannot run the configure array
array_number command again to configure the remaining space on the array.
Note the following points:
• The largest LUN size possible is 2TB.
•The configure array array_number command automatically sets the roles of the LUNs
that it creates on an SFS20 array.
• By default, the RAID redundancy is set to ADG, and the number of disks per group is set to 11.
These examples are further explained in Section J.5 in Appendix J.
5. Configure the arrays as required to support the number of file systems you intend to create, as shown
in the following example:
sfs> configure array 1,2 luns_size=33%,all
