Incomplete FPIN-LI tests

[johnmeneghini]

This branch contains the beginnings of an FPIN-LI blktest. tests/nvme/069 is a copy of tests/nvme/057 which is the basic ANA test.

Test Setup

See the blktests README.md for more information.

This test should be run against an upstream kernel with the appropriate patches applied to the fc_loop driver. In addition the following kernel config options should be enabled.

CONFIG_NVME_CORE=m
CONFIG_BLK_DEV_NVME=m
CONFIG_NVME_MULTIPATH=y
CONFIG_NVME_VERBOSE_ERRORS=y
CONFIG_NVME_HWMON=y
CONFIG_NVME_FABRICS=m
CONFIG_NVME_FC=m
CONFIG_NVME_TARGET=m
CONFIG_NVME_TARGET_DEBUGFS=y
# CONFIG_NVME_TARGET_PASSTHRU is not set
CONFIG_NVME_TARGET_LOOP=m
CONFIG_NVME_TARGET_FC=m
CONFIG_NVME_TARGET_FCLOOP=m

Running Tests

Tests must be run from root account.

Example:

Test status.

tests/nvme/069 - the nvme-fc marginal path handling test is currently incomplete and does not run because of dependencies on the fc_loop driver.

Example:

root@target-vm:/home/jmeneghi/repos/tests/blktests# NVMET_TRTYPES=fc ./check --cmd-trace tests/nvme/069
