NAME    [Toc]    [Back]

     grio - display GRIO reservation information

SYNOPSIS    [Toc]    [Back]

     grio [ -BCDFIPRSVa] [ -d device ] [ -f file ]
	  [ -s grio_stream_id] [ -v XLV_volume ]

DESCRIPTION    [Toc]    [Back]

     grio displays information about the active	GRIO reservations and
     statistics	on the GRIO subsystem.	Only one of the	options	BCDFIPRSV can
     be	specified on a single invocation of grio:

     -B	  Print	information about active GRIO reservations on a	given device.
	  Devices can be specified with	the -d or -a options.

     -C	  Print	the device path	and show active	GRIO reservations.  Devices
	  are specified	with the -d option. This only works for	disks.	Each
	  path component reported can be fed back to grio with the -d option.

     -D	  Delete the GRIO stream with the specified stream ID.	Stream IDs are
	  specified with the -s	option.	 This option can be run	only by	the
	  superuser.

     -F	  Print	the bandwidth information for all the devices in the device
	  path of the specified	logical	volume.	 Logical volumes are specified
	  with the -v option.  Each path component reported can	be fed back to
	  grio with the	-d option.

     -I	  Print	GRIO command statistics.  This option is assumed by default.

     -P	  Print	GRIO device path.  Devices are specified with the -d option,
	  and only applies to disks.  Each path	component reported can be fed
	  back to grio with the	-d option.

     -R	  Print	active GRIO reservations on the	specified file.	 Files are
	  specified with the -f	option.

     -S	  Print	information on all active GRIO reservations.

     -V	  Print	active GRIO VOD	reservation information	for specified volumes.
	  Logical volumes are specified	with the -v option.

     The following options are used to specify individual devices:

     -a	  This option specifies	all real time disk devices.

     -d	  Specifies a given device in the hwgraph name (reported by the	-P, -C
	  and -F options) or disk alias	name (/dev/rdsk/dks1d2s7) format. For
	  example, /dev/rdsk/dks1d2s7,
	  /hw/module/1/slot/io1/baseio/pci/0/scsi_ctlr/0/target/4/lun/0/disk,
	  /hw/module/1/slot/n1/node/xtalk/0/xbow.

     -f	  Specifies a given XFS	realtime file, for example /xfs1/realtime.

     -s	  Specifies a GRIO stream by the stream	ID, for	example, 03e4518e3ec2-101e-884c-080069027409.


     -v	  Specifies an XLV volume, for example,	/dev/xlv/xlv_1.
