FYI: Using NIM resource on other file systems than JFS or JFS2

[Hajo Ehlers]

How to use GPFS or another NFS exportable filesystem as a NIM resource
( tested on AIX 6.1 TL7 SP1 )

1) Use the force option “-F” of the “nim” command

Example: Creating a lpp_source on a GPFS using the force option
nim -Fo define -t lpp_source -a server=master -a location=/gpfs/nim/
lpp_source/aix71 aix71lpp

2) Export the variable NIM_ATTR_FORCE to yes which has the same effect
as the “-F” option of the nim command since the “-F” will set the
variable NIM_ATTR_FORCE to yes

Example: Creating a lpp_source on a GPFS setting the NIM_ATTR_FORCE
beforehand.
export NIM_ATTR_FORCE=yes ; nim -o define -t lpp_source -a
server=master -a location=/gpfs/nim/lpp_source/aix71 aix71lpp

3) The /usr/lpp/bos.sysmgt/nim/methods/c_stat which is used to
determine the valid file systems types for NIM does not use the ODM to
determine valid files systems for NIM . They are hardcoded within
c_stat.

4) The use of other file systems other than jfs or jfs2 is not a
supported solution by IBM.
