MPE Using the ARM Command Line Utilities for MPE Performing Disk Array Maintenance Tasks Changing SCSI Settings The SCSI settings control the transfer of information over the SCSI channel connecting the host and the disk array. The default SCSI settings listed in Table 21 have been chosen to work with all supported SCSI adapters, and in most cases should not be changed. NOTE! Before changing any SCSI setting, you should understand what the SCSI setting does, and what effect changing it will have on disk array operation. Be aware that using an incorrect SCSI setting may make it impossible for the host and disk array to communicate properly. In this case, it will be necessary to use the disk array control panel to return the SCSI setting to its original value to reestablish communication. To change SCSI settings, type: arraymgr { -W | -T | -P | -m | -r } {on|off} Changing the Controller SCSI ID Changing the SCSI ID directly impacts the operating system's ability to access the disk array. Before performing this task, check your operating system documentation for information on how to change the SCSI ID of a disk subsystem. To change the controller SCSI ID, type: arraymgr -C {X|Y} addr addr is the new address (0 - 15) for the indicated controller 147
