Description Bryn M. Reeves 2007-07-20 16:14:44 EDT
Description of problem:
The compiled in default priority callout for the Hitachi HDS SANs is incorrectly
specified without the full path in libmultipath/hwtable.c:

                .vendor        = "HITACHI",
                .product       = "DF.*",
                .getuid        = DEFAULT_GETUID,
                .getprio       = "mpath_prio_hds_modular %d",
                .features      = DEFAULT_FEATURES,
                .hwhandler     = DEFAULT_HWHANDLER,
                .selector      = DEFAULT_SELECTOR,
                .pgpolicy      = GROUP_BY_PRIO,
                .pgfailback    = -FAILBACK_IMMEDIATE,
                .rr_weight     = RR_WEIGHT_NONE,
                .no_path_retry = NO_PATH_RETRY_UNDEF,
                .minio         = DEFAULT_MINIO,
                .checker_name  = READSECTOR0,

This leads to errors like:

error calling out mpath_prio_hds_modular 65:32
error calling out mpath_prio_hds_modular 66:80
error calling out mpath_prio_hds_modular 65:32

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Enable multipath on a system attached to a Hitachi HDS SAN by commenting out
the blacklist {...} block in multipath.conf
2. Run multipath

Actual results:
Above errors

Expected results:
No errors, correctly determines path prio grouping & creates multipath maps

Additional info:
Easily worked around via multipath.conf device {...} blocks.

I have this patch running on 100s of machines here at Hitachi and in the field.

It is good.
