Measures reported by HPStOLibraryTest
HP StoreOnce Backup Systems can be configured as either a NAS or a VTL target appliance. VTL targets appear to the backup application as physically connected tape devices, with backup and recovery jobs managed in the same manner as with a physical tape device. These Virtual Tape Libraries enable administrators to more efficiently manage resources. Virtual Tape Libraries are recommended for customers in Fibre Channel environments, or where a continued investment in tape hardware and software is a key consideration. If the Virtual Tape Library suddenly becomes unavailable or stops abruptly, the data stored in that Virtual Tape Library may become inaccessible to the users. To ensure continuous availability of data, it is essential to monitor the status of each Virtual Tap Library in the target HPE StoreOnce Backup system. The HPStOLibraryTest test helps administrators in this regard!
This test auto-discovers the Virtual Tape Libraries on the target HPE StoreOnce Backup system and for each Virtual Tape library, this test reports the current status, health and replication health. Besides, this test also reports the amount of data that is stored before and after deduplication. Using this test, administrators can figure out the count of drives and Cartidges assigned to each Virtual Tape Library and the count of drives that are currently online. The detailed diagnostics reveals the replication role and deduplication ratio of each Virtual Tape Library.
Outputs of the test : One set of results for each Virtual Tape Library available on the target HPE StoreOnce Backup system being monitored.
