nas_cmd
Using the NAS EMC has partially changed the layout or format of Celerra internal
database and query
databases. This change can impact the use of awk or grep utilities
facility
when used in scripts that assume specific positions of fields in
databases.
To enable searching of the NAS database, Celerra has developed a
new query subsystem that appears as a hidden option on some of the
nas_commands. This query subsystem enables you to specify the
information you are interested in, allows you to format the output,
and is independent of the database format.
CAUTION
!
Do not use grep and awk to scan the database files. Database
positions may change and substrings may return false matches for
database objects.
