Virtual TapeServer 6.04.05 for NonStop Servers Release Notes

Known Issues | 17
 Ownership of files is changed if encryption software is run by root. If a program
that uses encryption software is run by the root account, ownership of critical files is
changed, which will prevent programs from running correctly under normal user
authority. The programs that must not be started as root include the following:
• ems_master.pl
• ems_mounts.pl
• ems_send.pl
• ems_telnet.pl
•hsmdelete.pl
•hsmget.pl
•hsmput.pl
• vtsisc_cancel.pl
• vtsisc_mount.pl
• vtsisc_unmount.pl
• vts_scratch_erase.pl
The most common symptom of this problem is that VTS will not be able to log into a host
server. Log messages may make it appear as if a password has not been set, though it has
been set since encrypted passwords cannot be decrypted. (TL-3377)
To determine if the problem is present, execute the following as root or bill and verify that
one or more files is owned by root: ls -l /home/bill/.gnupg
WORKAROUND: To correct the problem, execute the following command as root:
chown bill.bill /home/bill/.gnupg/*
 Segfaults occur during shutdown and reboot. A performance monitoring agent may
segfault during shutdown. This causes no system impact. (TL-3320)
 Corrupt virtual tape causes server to become unresponsive. If the VTS server
loses power during a backup, causing the corrupt cartridge, the backup will fail. (It is
likely that the host running the backup will log a failure message.) As a result, VTS may
become unresponsive. (TL-3512)
WORKAROUND: Erase the resulting virtual tape and rerun the backup.
 traceInit messages are logged to /var/log/messages. Messages similar to the
following are logged to /var/log/messages. These messages can be ignored. (TL-3151)
Jun 2 13:20:54 VTS06 slave: traceInit: Opening /proc/crds-trace
failed, No such file or directory
 Failures may occur if an autoloading pool contains an invalid cartridge. Only
valid cartridges should be added to pools within vaults. If other files are there,
inconsistent or unpredictable behavior may occur. (TL-3125)
WORKAROUND: Restart the Tapeserver service.
 Interrupt requests are disabled while the server is idle. VTS may broadcast to all
terminals that it is disabling unused interrupt requests (IRQs). These warnings may be
safely ignored. (TL-1997)
