Re: LTO Tape Life
Well, if the information is simply not available, can someone point me to a document saying so? Our brilliant auditors are requiring proof one way or another in our DR documentation. -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Wanda Prather Sent: Saturday, June 21, 2008 12:55 PM To: ADSM-L@VM.MARIST.EDU Subject: Re: [ADSM-L] LTO Tape Life I know, I just hate manual processes.

Re: LTO Tape Life
Ditto. John, there is nothing in the 3584 or in TSM that will give you what you want, if the tapes are ejected for vaulting and leave the 3584. The only way we're going to get this info, is if somebody provides an API to read from the cartridge chip. I'm kinda suprised nobody has done that yet -- except as Tom says, the cartridges tend to last a long time anyway.

Re: LTO Tape Life
The TS3500 internal web server provides some information about the cartridges. Not sure what they really means. It does tell you the number of read and write errors for both LTO and 3592 cartridges from the cartridge memory. Go to your TS3500 library internal web server Expand +Cartridges Select Data Cartridges Select Download mount history(.csv) This will pull up a spreadsheet with the last 100 mounts for the library. Information include are Mount History Mount Life Tape Alert Mounts WRetries Media Media Media Date and Time VolSer Frame Drive LogLib EAddr _1-64 Count Count Mount WPerms RRetriesRPerms Rating Write Media Media Media Drive Media Ports Port0 Port1 Rsvd Perf Count Count Count _1-255 _1-255 _1-255 _1-255 _1-255 _1-255 Util% Read Capacity Crypto ERPsBurst Buffer PerfERPsBurst Buffer Total Writes Control Status Rekey Impct% Util% Util% Util% Impct% Util% Util% Util% Util% Util%

Re: LTO Tape Life
It would probably have to be associated with a libvol instead of a volume. Volumes get created and deleted as they move out of and back into the scratch pool. I'd like to see the stats that are currently associated with volumes instead associated with libvols (mounts, read and write errors, passes).
