HP-UX Using the ARM Command Line Utilities for HP-UX Viewing the Disk Array General Configuration Settings Parameter Default Setting Description Unit Attention ENABLED Indicates whether the disk array should signal a Unit Attention condition immediately following power-on or reset. Disabled, indicates the disk array will not signal unit attention. Enabled indicates the disk array will signal unit attention. Disable Remote Reset ENABLED Controls the bus reset behavior of the second controller when a SCSI reset (reset signal, BDR or Reset Disk array command) is received in the first controller. When this bit is disabled, the second controller will assert the bus reset signal to indicate that all outstanding requests were cleared in response to the reset. When this bit is enabled, the second controller will not assert the SCSI reset signal to indicate the commands were cleared. Hosts that cannot tolerate target bus resets should enable this setting. Secondary Controller DISABLED Controls the behavior of the secondary controller with Offline respect to bus selection. When disabled, any secondary controller present will respond to host selection. When enabled, the secondary controller will remain off-line until a failure of the primary controller is detected (at which point it becomes primary). Only the primary controller will go on-line. Very Early Busy DISABLED Controls the behavior of the disk array with respect to SCSI bus selection during the early stages of the initialization sequence (i.e., from about three seconds after reset until about fifteen seconds prior to initialization completion). When disabled, the disk array will ignore SCSI bus selection until the late stages of initialization. When enabled, the disk array will accept selection during early initialization and will return BUSY status until the late stages of initialization. Queue Full Threshold 1952 Specifies the target queue depth beyond which the disk array will return QUEUE FULL status to subsequent host requests. 67
