SHIFT at the MPI

currently available are the following topics:

• General Overview (from CERN)
• SHIFT at the MPP

• IBM LoadLeveler - a facility for executing batch jobs on UNIX Workstations

The SHIFT commands:

• sfgc - deallocate space on disk
• sfget - create file in diskpool
• sfrm - delete file from diskpool
• sfsh - issue shell commands in each fs of a diskpool

• dumptape - dump a tape and analyze its contents
• tpread - schedule the copying of data from tape to disk
• tpwrite - schedule the copying of data from disk to tape

• reserv - reserve tape resources
• rls - release tape resources
• tpinfo - get tape file information from header labels and mount requests; get also the tape drive name.
• tplabel - initialize a new blank tape
• tplblinfo - get information from header labels
• tpmnt - ask operator to mount a tape and position the tape
• tprstat - give the device group reservations for all tape users
• tpstat - give the status of all tape units

• stagealloc - allocate space in a disk pool
• stagecat - put an entry in the stage daemon catalog for an existing file
• stageclr - remove staged files
• stagein - allocate space in a disk pool and copy files from tape to disk or from disk to disk
• stageinit - tells stgdaemon to reread the pool configuration file
• stageout - allocate space and store the option values in the stgdaemon catalog for use by stageput later.
• stageput - copy disk files to tape
• stageqry - give the status of all staged tapes
• stageupdc - update the stager catalog
• stagewrt - copy existing files from disk to tape or from disk to disk

• copytape - copy files or partial files from one or more input tapes to one or more output tapes
