applicationthat creates a internet domain socket. If there is a need for the Mover to use
larger socket buffers, a better solution is typically to use the HPSS network options
configuration file, which provides better granularity of control and only affects HPSS
subsystems.
◆RPC_UNSUPPORTED_NETIFS - Verify that only the desired network interfaces are
being utilized by DCE.
◆TapeDevices - Verifythat the tape devices appear to be correct (e.g., if a 3590 is attached
toan AIX machine, it should show up as a 3590, not “Other SCSI tape”). Verify that all
areconfigured to use variable block size (if they are to be controlled by an HPSS Mover
in any case).
◆Filesystems - Verify the requisite file systems are mounted and have enough space -/
var/dceon all nodes and /var/hpss and the filesystems for the TRB and LA files on the
core server. I’ve lost track – are there others (/var/hpss on Mover nodes?)?
◆CrontabEntries - Verify that rmxcred (all nodes) and the sfs backups (core server only)
are covered. If not in crontab, then how?
◆Device Location/Configuration Information - Verify that the busses are reasonably
well used – e.g., one SCSI adapter isn’t connected to two tape drives while another
adapters is unused.
◆Tape Device Info - Verify that variable block sizes and device buffering are enabled.
Compression is also usually enabled.
• All tables documenting disk and tape performance results.
• SFS configuration information (Note: Thelsencina and lsencina.ksh scripts are from the
deployment tools package).
To generate the SFS configuration information locally, issue the following on each SFS
server node:
root% dce_login hpss_ssm -k /krb5/hpss.keytabs
root% cd /opt/hpss/tools/deploy/bin
root% lsencina > /var/hpss/stats/lsencina.out
root% more /var/hpss/stats/lsencina.out
To generate the SFS configuration information, store it locally in/var/hpss/stats/
lsencina.out, and have it automatically emailed to IBM Houston, issue the following:
root% lsencina.ksh
root% more /var/hpss/stats/lsencina.out
• Descriptionof SFS backup procedures, including printouts of all SFS backup configuration
files and local/custom scripts. Include information such as TRB file sizes, frequency of
backups, number of TRB files generated per day, number of backups retained, etc.
• Description of DCE backup procedures (including frequency)
• Disaster Recovery Plan, including:
