CAUTION: Set the initiator ID on a SCSI adapter carefully. Duplicate SCSI IDs on a SCSI bus can result in bus hangs, system hangs, and system panics. The mptconfig command will attempt to verify that no targets are using the specified ID before the change is allowed; however, in the case of multi-initiator (shared bus) configurations, the mptconfig command cannot detect the presence of other initiators on the SCSI bus. Use the ioscan command on any servers connected to the same SCSI bus to verify that the init_id selected is free, before using the mptconfig -ioption.

NOTE: The In Use Device column is only displayed on systems running HP-UX 11i v3.

Using Common mptconfig Command Line Options

This section lists the mptconfig command line options to change common A7173A SCSI settings online:

Use the -roption on the mptconfigcommand to change the transfer rate for the A7173A adapter. For example:

# mptconfig -r ultra160 /dev/mpt14

Confirm: Do you want to change scsi parameters (y/[n]): y

Status

[Successful]

#

Use the -woption on the mptconfig command to change the SCSI bus width. For example:

# mptconfig -w narrow /dev/mpt14

Confirm: Do you want to change scsi parameters (y/[n]): y

Status

[Successful]

#

Use the -toption on the mptconfig command to change the SCSI ID of SCSI target devices that do not automatically configure SCSI IDs.

NOTE: In most cases, target device SCSI IDs are set automatically by the storage enclosure or by a switch on the storage enclosure. See the documentation for the peripheral device to determine how to set its SCSI ID.

Use the -doption on the mptconfig command to set the SCSI parameters on the A7173A adapter to the default values. For example:

# mptconfig -d /dev/mpt14

Confirm: Do you want to change scsi parameters (y/[n]): y
