Devices connected through SCSI Bridge don’t
reconnect after VTC server maintenance
Context
Maintenance has been performing on the VTC server that required either rebooting
the server or stopping and restarts the VTC (FC) Emulator service. At the service
restart time, the NonStop TAPE devices associates to virtual device were not stopped
and one or many following symptom appear:
• Automatic load failed with NO RESOURCE available reason
• In SCF, TAPE operations failed with error:
o STORAGE E-00010 File system error: 40, call: WRITEREADX, file:
$ZNET
o STORAGE E00045 I/O process is busy.
• NonStop TAPE device(s) appear(s) FREE but Virtual Tape device(s) status is
INACTIVE or ACTIVATED for more than 30 seconds in the “Status for
NonStop node” page in the BackPak User Interface.
Solution
• Make sure the Bridge firmware is at revision (or higher):
o etinet.SFC4200.v3.01.13.rc1 (Sep 20 2012 09:21:29)
• Log on the Bridge Web console and select Reboot System from Bridge
Control and then acknowledge the request. Wait for the login screen to re-
appear.
WARNING from SQL [6008]: Statistics …
This warning can occasionally be reported by a Catalog Sync Export or Import
process accessing a DSM/TC catalogue.
This warning does not invalidate the process results; HP manuals explain how to
avoid this message by the SQLCI UPDATE STATISTICS command. It is suggested to
run it on all tables of the VOLCAT and the FILECAT.
Some SQL operations (DDL) are not allowed during the UPDATE STATISTICS. The
safest is to avoid using the DSM/TC catalogue while UPDATE STATISTICS runs.
i.e. : no tape activity, no MEDIACOM session running, no BackPAK GUI.
Naturally the operator must be allowed to read the involved table and to update the
SQL catalog (metadata tables in the subvol).

(To get the volcat-subvol name)
