Hi Devesh
If a user writes the file such that it is legal (see below) OpenSM will use it.
When a STANDBY SM gets mastership it has two choices:
a. Use the LIDs from the fabric
b. Enforce the assignments provided by the guid2lid file
The option
Legal means:
1. there are no LID conflicts
2. lid range start is aligned with 2^(LMC)
NOTE that the end of the range can extend beyond start + 2^(LMC) - 1
/var/cache/osm/opensm.opts:
# If true honor the guid2lid file when coming out of standby
# state, if such file exists and is valid
honor_guid2lid_file FALSE

Hi Hal Thanks for replying.
This setisfies my needs if user can define his own guid to lid
mapping.
whether in this file user can define his own guid to lid mapping?
To my knowledge it's not used that way in general but that could work if
consistent with the OpenSM LID policy (e.g. LMC, etc.).
consistent with the OpenSM LID policy means what? Is it that, That each GUID
sholud have unique LID range?
The format of the file is as follows:
0x0008f10403960985 0x0007 0x0007
0x0008f10400410015 0x0003 0x0003
(e.g GUID, min LID, max LID so the above is for LMC 0 which is the
default).

There is a file it creates with these in it so they can be
reused
subsequently. It is /var/cache/osm/guid2lid.
opensm -h has the following option:
-c
--cache-options
Cache the given command line options into the file
/var/cache/osm/opensm.opts for use next invocation
The cache directory can be changed by the
environment
variable OSM_CACHE_DIR
Is that suitable for your needs ?
