Hello, I am searching for some advice on how to determine LTO6 tapes
health in order to prevent failing backups because of faulty tapes.
We are using IBM TS libraries with LTO6 cartridges, managed by CentOS
servers. LTO Ultrium tapes have cartridge memory, which holds some
useful information about tape usage. There are not many tools to read
and parse this data. We can read some statistics with ITDT (IBM Tape
Diagnostic Tool) [1], which is useful to measure read and write retries.
This can be an indicator of a tape nearing its EOL. Cartridges memory
should also provide stats of last four usages, which is helpful to
identify if there is a problem with cartridge or drive, when errors
occur.[2] I cannot find any tool to read this stats, except if I read
correct attributes with ITDT, but so far that wasn't successful.
How do you guys determine the quality of used tapes and manage tapes
lifecycle? Any advice on this subject is appreciated.
Best regards!
