SMF Catalog File Recovery
SMF Catalog File Recovery

SMF catalog files are Enscribe files protected by TMF (HP highly recommends
TMF file recovery protection). However, recovery of catalog files must be done in
distinct phases to ensure that the integrity of the SMF subsystem and databases is
maintained..

== Scan each line, look for the 3rd token to be a number. If it’s a number,
== we have a findfiles entry. Format the backup line if this file is not
== on the user specified physvol.

#unframe
== END OF SMRECOV
Note. Due to the critical nature of SMF catalog files, HP highly recommends that SMF
catalogs be given full TMF recovery protection by taking frequent on line dumps and placing
them on mirrored volumes.
