grio(1M)grio(1M)NAMEgrio - display GRIO reservation information
SYNOPSISgrio [ -BCDFIPRSVa] [ -d device ] [ -f file ]
[ -s grio_stream_id] [ -v XLV_volume ]
DESCRIPTIONgrio 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.

grio(1M)grio(1M)-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.

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.
