xscsiHostIdSet [channel], [id]
The xscsiHostIdSet command sets the Host ID for a specified Ultra 2/3 SCSI
Channel.
Channel numbers 1 - 6 (Ultra2/3 SCSI)
Id numbers can be0-15
Gateway > xscsiHostIdSet 5,9
Host Id set to 9 for XSCSI 5
will take effect upon reboot
value = 0 = 0x0

To set Host IDs for Ultra SCSI channels, see the scsiHostIdSet
command. xscsiRescan
The command xscsiRescan requests a SCSI rescan for new devices on the Ultra 2/
3 channels 1 - 6. If channel is specified (1, 2, 3, 4, 5, or 6), then only that channel is
scanned. Otherwise, if channel is not specified or if channel is 0, then all channels are
scanned.

Done

Notes:
1. 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.
2. If a channel is specified, that channel is scanned and the prompt is returned
on completion. If no channel is specified (or 0 is specified), SCSI Channels 1
through 6 are scanned in sequence and the prompt is returned on completion.
3. 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).
4. 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

Attention: You must reboot the ADIC Gateway after executing this com-
mand for the new settings to take effect .
