SET GLOBALS is used to set the expand priority, the
                read/write ratio, and the system name.

                Format:
                        SET GLOBALS / <qualifiers>

1  –  Parameters

                None

2  –  Qualifiers

2.1    /EXPAND_PRIORITY

                Specifies the expansion priority for the RAID Volumes.

                Format:
                        /EXPAND_PRIORITY=(LOW | MEDIUM | HIGH)

                Description:

                EXPAND_PRIORITY=HIGH-the expand priority. Used when
                expanding an array to set the priority of array
                expansions in relation to input/output operations.
                See below for detailed information about these
                settings.

2.2    /READ_CACHE

                Specifies the percentage of cache to be used on READ
                commands.

                Format:
                        /READ_CACHE=(AUTOMATIC | #percent)

                Description:

                READ_CACHE=50-the read cache. This value must be
                between 0 and 100.

2.3    /REBUILD_PRIORITY

                Specifies the Rebuild priority of the RAID Volume.

                Format:
                        /REBUILD_P=(LOW | MEDIUM | HIGH)

                Description:

                REBUILD_PRIORITY=HIGH-the rebuild priority. Used
                when rebuilding an array to set the priority of an
                array rebuild in relation to input/output operations.
                Low-expansion or rebuild takes place only when the
                array controller is not busy handling normal I/O
                requests. This setting has minimal effect on normal
                I/O operations. However, there is an increased risk
                that data will be lost if another physical drive
                fails while the rebuild is in progress.

2.4    /WRITE_CACHE

                Specifies the percentage of cache to be used on WRITE
                commands.

                Format:
                        /WRITE_CACHE=(AUTOMATIC | #percent)

                Description:

                WRITE_CACHE=50-the write cache. This value must be
                between 0 and 100.

2.5    /SYSTEM_NAME

                Specifies the name to be assigned for the controller.

                Note: This qualifier is not supported for Smart Arrays.

                Format:
                        /SYSTEM_NAME=(name)

                Description:

                SYSTEM_NAME="XXX"-the system name, where XXX represents
                any user defined phrase, up to 20 alphanumeric characters.

2.6    /VERBOSE

                Provides logging that can be interpreted by engineering.

3  –  Examples

                MSA>  SET GLOBALS/EXPAND_PRIORITY=HIGH/REBUILD_
                      PRIORITY=HIGH/SYSTEM_NAME="XXX"/READ_CACHE=50/
                      WRITE_CACHE=50

                      Note: Read_cache plus write_cache must equal 100.

                      Example MSA$UTIL response for SHOW GLOBALS:

                          Controller: _$1$GGA1002: (DEFAULT)
                          Global Parameters:
                          System Name: ITA8.2-1
                          Rebuild Priority: high
                          Expand Priority: low
                          Total Cache: 256MB
                          25% Read Cache: 64MB
                          75% Write Cache: 192MB
