scsiRescan [channel]
The command
scsiRescan
requests a SCSI rescan for new devices. If channel is specified (1 or 2), then
only that channel is scanned. Otherwise, if channel is not specified or if channel is 0, then all channels are
scanned.
SNC4000 > scsiRescan 2
Done
value = 0 = 0x0
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. An example of this is a disk that requires a SCSI Start Unit command to become ready. (Tape
and Changer devices and Disks 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.
