fields will display the current value. Change the accounting bits such that if the initial value
is 1 then the new value will be 2 and conversely if the initial value is 2 then the new value
will be 1.
At this point, the HPSS system has no accounting metadata for existing files. Any new files that are
added will generate new acounting metadata but existing files need to have their accounting metadata
created using an additional conversion routine (acct_convert).
Since the final step of the accounting conversion is time-consuming, we recommend that it be
postponed until a later time and the Start HPSS 6.2 Servers step, Section 6.3.20.4: below, be
performed next. Verify that HPSS functions properly and that the conversion has been successful
before performing the third and final step in converting the accounting metadata:
3. After it is clear that the system will not be reverted, use the /opt/hpss/bin/acct_convert utility
to regenerate the accounting metadata for each subsystem's existing files. This utility must
be run once for each subsystem and will run for some time depending upon the size of the
HPSS system (possibly for multiple days). If a restart is necessary, built-in checkpoint
capabilities will allow it to resume processing. Be sure to run the utility to completion, and
check the utility's output to ensure that it has completely converted all the necessary
subsystem accounting metadata
6.3.20.4. Start HPSS 6.2 Servers
If using unix authentication, all HPSS servers must run as root. If necessary, modify each server's
configuration's Username to root using the SSM Server Configuration window.
Using the SSM client, start up all the configured HPSS 6.2 servers. After starting other HPSS
servers, error messages shown on the console include:
Error in stat of Keytab File, /var/hpss/etc/mm.keytab, 2
To resolve this problem, create an empty file owned by root with 644 permissions.
6.3.21. Verify 6.2 System
If there is a possibility that the HPSS system will be reverted back to the 4.5 or 5.1 level, do
not attempt to continue with the remaining upgrade steps. Doing so may result in corruption
of the 4.5 or 5.1 user data
Perform the following steps for each root and non-root subsystem:
• Read existing files using each configured user interfaces
• Write new files to HPSS using each configured user interfaces
• Restore all execution permissions for the following binaries in the /opt/hpss/bin directory:
• hpss_mps
• repack
• reclaim
• recover
• shelf_tape
• shelf_tape_util
