SAS expansion enclosure worksheet

If your system increases the amount of internal storage by adding optional SAS expansion enclosures, you must record the configuration values during the installation process.

Complete the following tables based on your particular system before system installation.

Table 1. Configuration values - SAS enclosure 1
Configuration setting	Value	Usage in CLI
MDisk group name		`mkmdiskgrp -name mdisk_group_name -ext extent_size`
MDisk extent size in MB		`mkmdiskgrp -name mdisk_group_name -ext extent_size`
Distributed RAID level (DRAID5 or DRAID6)		`mkdistributedarray -level DRAID_level -driveclass driveclass_id -drivecount x -stripewidth x -rebuildareas x mdiskgrp_id \| mdiskgrp_name`
`driveclass_id` - the class that is being used to create the array, which must be a numeric value.
`drivecount` - the number of drives to use for the array. The minimum drive count for DRAID5 is 4, while the minimum drive count for DRAID6 is 6.
`stripewidth` - the width of a single unit of redundancy within a distributed set of drives. For DRAID5, it is 3 - 16; for DRAID6 it is 5 - 16.
`rebuildareas` - the reserved capacity that is distributed across all drives available to an array. Valid values for DRAID5 and DRAID6 are 1, 2, 3, and 4.
