grio(1M)							      grio(1M)

NAME
     grio - display GRIO reservation information

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

DESCRIPTION
     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, 03e4518e-
	  3ec2-101e-884c-080069027409.

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

FILES
     /etc/grio_disks

NOTES
     To make grio more secure, grio has to be run with the priviledge of
     CAP_DEVICE_MGMT or as root.

     The guaranteed rate I/O capabilities described in this man page refer to
     the version one GRIO implementation. Refer to grio2(5) for information
     covering the newer GRIO Version 2 implementation which supports both
     local and clustered XVM volumes.
