HP StoreEver TapeAssure Software - Manual (Page 94)

Will TapeAssure disrupt backups?
No. Even in the standalone configuration, the TapeAssure data is only pulled from the drive once
every six hours and it only takes around 10 seconds to do so. Even if the data is pulled more
frequently and during the backup, the only affect is that the backup slows down during the data
extraction (10 seconds) and then returns to normal data rates.
The drive logs are extremely rich and contain all the data for the backup process in a single
extraction at the end. There is no need for regular polling as used by other tape drive monitoring
solutions.
HP has extensively tested TapeAssure with all the major backup applications.
Is HP TapeAssure compatible with my backup application?
Yes. TapeAssure is independent of backup applications.
Can I stop the LTT Service pulling tickets?
Yes. Use the Windows Computer Manager service management application and pause or stop
the LTT Service. The service can be re-started at any time.
Is TapeAssure monitoring in-band or out-of-band?
The LTT Service for standalone tape drives accesses the tape drive through the host interface port
and is therefore in-band. however this is done only once every six hours and is very fast.
When should I install the LTT Service?
The LTT Service should be installed as part of the initial set up of the server or backup system. It is
an always-on monitoring system and diagnostics, unlike the 4.x L&TT version, which is a post-issue
diagnostics application. Once the LTT Service is installed and running it needs no further
maintenance. Data is simply viewed via the L&TT WebGUI.
Can I set up TapeAssure to send me the service actions by e-mail?
No, this is not available from L&TT at this time. For tape libraries, you can use Command View TL
to be notified of service actions.
What if I want to change the WebGUI server that is collecting monitoring
data?
The L&TT WebGUI server is set up as a configuration for the LTT Service. If the URL of the server
is changed in the configuration file the TapeAssure data will be sent to the new location.
NOTE: If the URL is invalid or there is a problem with the WebGUI server, the TapeAssure data
will remain on the backup server until the problem is resolved. Data is not lost unless the capacity
set in the configuration is exceeded – at which point you must remove the old data to make way
for the most recent.
Why aren’t my drives being monitored?
There are a number of reasons why drive data might not appear on the WebGUI or Command
View TL TapeAssure tab. Follow the checks in
“Troubleshooting the LTT Service” (page 97) which
trace the whole process from drive discovery through to presentation on the Command View TL
GUI or L&TT WebGUI.
