ScsiResetDisableGet channel | ADIC SNC 5100, Scalar 1000 specification

SNC 5100

value = 0 = 0x0 SN60023 >

Rescanning a SCSI bus may delay I/O commands pending on that bus for several seconds. Do not rescan SCSI buses when this delay may not be tolerated. When possible, only scan the bus where a new device has been added.

When a device is discovered, there may be further device specific initialization that continues after the scan has completed in which case the device may not show up immediately when you issue the fcShowDevs command. Tape and Changer devices that indicate Ready status are available on scan completion.

If a SCSI target device should require replacement, remove the old device, set the new device to the same SCSI bus ID as the old device and attach it to the same channel. Rescan the channel to update the configuration data. The new device should be available to host systems with the same LUN as the old device.

scsiResetDisableGet [channel]

The scsiResetDisableGet command displays the SCSI Bus Reset On Power Up is enabled. False means that SCSI Bus Reset On Power Up is disabled.
