Virtual TapeServer 8.2 Release Notes

Troubleshooting | 61
VTSPolicy
 Incremental backup backs up all cartridges. Any incremental backup backs up all
cartridges, even unchanged cartridges, within the requested file space. This problem is
due to the fact that a virtual cartridge contains user data and metadata. VTS often
updates the metadata even when the user data has not changed, causing the change time
(ctime) on the file to be updated; this is what causes the file to be backed up even if the
user data is unchanged. (TL-2155, EAR 4456)
Utilities and services
 CLIM does not see more than 8 LUNs after changing the tape type. This occurs if
VTS is started after device discovery. (TL-6777)
WORKAROUND: Device discovery on the CLIM can be best accomplished by first
starting VTS, then connecting the CLIM. Done this way, devices should be discovered
correctly. Finally, the device may be mapped with the CLIM to the NonStop.
 CLIM device discovery is fragile. Best practice is to set up and connect VTS to the
CLIM. When VTS is configured and ready, reboot the CLIM. All LUNs will be viewable
after this CLIM restart, and then map the LUNs. This is only necessary for the initial
configuration and setup of the CLIM. (TL-5582)
 /usr/local/tape/bin executables cannot be run as root. The programs in /usr/local/
tape/bin must not be run as root unless otherwise specified. If this is done inadvertently,
check the ownership of the files in /home/bill/.gnupg and ensure that they are owned by
the 'bill' account and have group ownership of 'bill' as well. Failure to observe this
precaution may cause a number of operational problems including failure to properly
process mount requests. (TL-2367)
