NAME¶
nvme-resv-report - Send NVMe Reservation Report, parse the result
SYNOPSIS¶
nvme resv-report <device> [--namespace-id=<nsid> | -n <nsid>]
[--numd=<num-dwords> | -d <num-dwords>] [--eds | -e]
[--raw-binary | -b]
[--output-format=<fmt> | -o <fmt>] [--verbose | -v]
[--timeout=<timeout> | -t <timeout>]
DESCRIPTION¶
The Reservation Report command returns a Reservation Status data structure to host memory that describes the registration and reservation status of a namespace.
The size of the Reservation Status data structure is a function of the number of controllers in the NVM Subsystem that are associated with hosts that are registrants of the namespace (i.e., there is a Registered Controller data structure for each such controller).
OPTIONS¶
-n <nsid>, --namespace-id=<nsid>
Retrieve the reservation report structure for the given
nsid. This is required for the character devices, or overrides the block nsid
if given.
-d <num-dwords>, --numd=<num-dwords>
Specify the number of Dwords of the Reservation Status
structure to transfer. Defaults to 4k.
-e, --eds
Request extended Data Structure: If this bit is set to a
1, then the controller returns the Extended Data Structure.
-b, --raw-binary
Print the raw buffer to stdout. Structure is not parsed
by program.
-o <fmt>, --output-format=<fmt>
Set the reporting format to normal, json or
binary. Only one output format can be used at a time.
-v, --verbose
Increase the information detail in the output.
-t <timeout>, --timeout=<timeout>
Override default timeout value. In milliseconds.
