NAME
vparutil — get and set SCSI parameters for SCSI controllers from a virtual partition
SYNOPSIS
vparutil -a
vparutil -d
dev_path
vparutil -g
dev_path
vparutil -s
dev_path
[-i
scsi_id]
[-r
scsi_rate]
DESCRIPTION
The
vparutil
command gets and sets SCSI parameters for SCSI controllers within
a running virtual partition. When setting the SCSI parameters using the
-s
option,
the virtual partition which owns the specified SCSI controller must be in
the down state. If not, the command will fail with the appropriate error
code.
The SCSI parameters for a given SCSI controller must first be set
(from the firmware BCH prompt or using the
-s
option) before the parameters can be retrieved using the
-g
option.
Only a superuser can execute the
vparutil
command.
Options
vparutil
recognizes the following command-line options:
- -a
Displays all entries in the SCSI table.
- -d
Deletes an entry for the specified SCSI controller at
dev_path
from the SCSI table.
- -g
Gets the SCSI parameters for the specified SCSI controller at
dev_path.
- -s
Sets the SCSI parameters for the specified SCSI controller at
dev_path.
Operands
vparutil
recognizes the following command-line operands:
- dev_path
The device path of the SCSI controller.
- id
The SCSI ID for the specified controller (defaults to 7).
- rate
The SCSI rate for the specified controller. This parameter can have
one of two values,
fast
and
ultra,
for the corresponding fast-wide and ultra-wide SCSI interfaces.
EXAMPLES
Set the SCSI ID for controller at 0/0/2/0 to 3 with the fast-wide rate:
vparutil -s 0/0/2/0 -i 3 -r fast
RETURN VALUE
- 0
Successful.
- 1
Invalid SCSI controller specification.
- 2
Invalid SCSI ID.
- 3
Could not communicate with virtual partition monitor.
- 4
Virtual partition which owns SCSI controller is not in down state.
- 5
Internal firmware call failed.
- 6
Other error.
