Administrative T asks 1-4 System T asks 600716 Re v A Interface to Vo l S e r v After both FileSe rv and V olServ have been installed and initially configured, drive pool and association of a MediaClass group with a library must be established within V olServ for FileSe rv communica tions.
Administrative T asks 600716 Rev A Syst em Tasks 1-5 System T asks Associate MediaClass with Libra ry On SGI systems, there are fifty four MediaClass names. Each MediaClass has the following form: FileServID_mediatype_mediaclasstype There are ten possible values for FileServ ID: F0 through F9.
Administrative T asks 1-6 System T asks 600716 Re v A • F0_D2S_MIGRATE • F0_D2S_REMOVE Register the Configuration Before FileSer v can operate properly , the physical configuration of the system must be defined within FileServ . This procedure is accomplished during or after FileServ instal lation.
Administrative T asks 600716 Rev A Syst em Tasks 1-7 System T asks • T runcation policies for files and media types associated with the DataClass group.
Administrative T asks 1-8 System T asks 600716 Re v A Media Under FileSer v Management Befor e data can b e copied f rom disk t o tape, the t ape medi a must be in place. The media should be properly label ed and entered into a storage subsystem b y a V olServ operator be fore entering media into the FileServ database.
Administrative T asks 600716 Rev A Syst em Tasks 1-9 System T asks Create Migration Policies Migration polici es initiate movement of fi le data from disk to tape. The following types of policy can be run: • Store data to tape (base d on DataClass param eters).
Administrative T asks 1-10 System T a sks 600716 Rev A Routine Processing Part of the FileServ system routine processing includes: Sto re a n d T runcate Files Policies for storage and for data truncation are run a s part of routine system processing.
Administrative T asks 600716 Rev A System Tasks 1-11 System T asks FileServ database maintenance is part of routine system processing. FileServ uses a RAIMA database to store and track information about the files under FileServ . The RAIMA database is embedded within FileServ and automatically starts when File Serv starts .
Administrative T asks 1-12 System T a sks 600716 Rev A When the checkpoint script runs, it tars the entire contents of the Fil eServ dat abase to a separate f ile system . After t his process is completed, it zeros out the journal file. If the journaling file system becomes full, processing stops.
Administrative T asks 600716 Rev A System Tasks 1-13 System T asks The table below shows the suggested database maintenance intervals for each da tabase utility . Although FileSe rv must be terminated, the Lock Ma nager process must be active, to run the checkDBALL script.
Administrative T asks 1-14 System T a sks 600716 Rev A keyBuildAll The $FS_HOME/uti l/keyBuildAll script rebuilds all the key files for the RAIMA database. Rebuilding the file keys is a two step process that also rebalanc es the B-tree structure of the database.
Administrative T asks 600716 Rev A System Tasks 1-15 System T asks The utilities that operate on spe cific file systems are: blockpos, dirdb, fileattr, filecmnt, filecomp and filexpir . All of the utilities, with t he exception of keytest ,h a v et w o modes: • Command Line Mode.
Administrative T asks 1-16 System T a sks 600716 Rev A First, you check the devdb table for the entry containing /test2 . Notice there i s a field c alled “ device key ” associat ed with /test2 . This is the value you will use for device specific table utilit ies that are associ ated with th e /test2 file system.
Administrative T asks 600716 Rev A System Tasks 1-17 System T asks Intera ctive Mode T o start a utility in Inte ractive Mode, incl ude the -i option on the command line. If the -i option is used, F ileServ ignores the -k key option. In Interactive Mode, a menu displays with options valid for the specified utility .
Administrative T asks 1-18 System T a sks 600716 Rev A In addition, there is always an option to query on one or more unique keys. When entering an option, you may enter as many options on the command line as you like. However , only the very first characte r is accepted a s the command.
Administrative T asks 600716 Rev A System Tasks 1-19 System T asks • Heavy storage, retrieval, modification, crea tion, or deletion of files in migra tion directories . The advantage to taking extra checkpoints is that recovery from database corruption is much faster and more reliable.
Administrative T asks 1-20 System T ask s 600716 Re v A Run this command only if the archived f ile systems are newer than t he restored databa se and the journal files have been pr eserved. The restore.pl command will not replace the old journal, so no other preparatory work should be needed if the journal file has been preserved.
Administrative T asks 600716 Rev A System Tasks 1-21 System T asks Run a fsmedinfo -l report to verify all file s deleted from media. If files still exist, rerun the fsclean c ommand. The fsundelete command allows recovery of removed or modified copies of files as long as an entry exists in the trashcan.
Administrative T asks 1-22 System T ask s 600716 Re v A Sta r t u p a n d Shut down The following startup modes exist for FileServ: • Normal .
