Parameter Summary Tables

This appendix lists the firmware parameter settings for both the FC and SCSI arrays. You can fine-tune your array by making changes to these settings. It also lists the parameter defaults that you should not change unless advised to do so by technical support.

Topics covered include:

Introducing Default Parameters

Basic Default Parameters

Default Configuration Parameters

Default Peripheral Device Parameters

Default System Functions

Keeping Specific Parameter Defaults

Introducing Default Parameters

Although the factory defaults provide optimized controller operation, you might want to fine-tune your array through minor modifications to the following parameters listed.

Some parameters can be changed only at the initial array configuration; other parameters can be changed at any time. Note the listing of parameters defaults that should not be changed unless directed by technical support.

Note - For customer convenience, these tables apply to both the Sun StorEdge 3310 SCSI array, using firmware version 3.25, and the Sun StorEdge 3510 FC array, using firmware version 3.27.
