TapeAlert goes back to DLT7000 days (late '90s) IIRC, but I do remember firmware updates for some drives which added TapeAlert or perhaps didn't implement it the way HP specified--so don't overlook the firmware possibility if your drives don't have TapeAlert as-is. ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu

Yes, our manufacture recommended we clean our tape drives based on usage hours.

Tim, I ran across that while looking for details on drive compression. I think the best writeup I found was on Overland's site and was on LTO3s (make allowances for failing memory, please). I was most surprised to find that the drive has its own little nose-wiper which, when it senses the need, physically runs a little cleaning pad or brush over the head, then retracts out of the way. The writeup went into some depth, including how it rejects any but the correct cleaning tapes, how it rejects even the correct cleaning tape if the drive doesn't think it needs to be cleaned, and how the primary cleaning mechanism was the drive built-in wiper, not a cleaning tape. All this effort to avoid cleaning when not necessary reflects what someone pointed out early in this thread--cleaning tapes are unburnished tape, hence more abrasive to get the crud off, but once the crud is gone, the abrasives start removing head material. In the olden days (reel-to-reel, "real" tape drives), 91% isopropyl alcohol and a Q-tip, cloth, foam pad or tubegauze worked just fine for tape and disk heads. :-) ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu

Re: [Veritas-bu] Drive Cleaning Frequency for SSO Drives
NBU will clean on two tapealerts - 20+21 CLEAN_NOW and CLEAN_PERIODIC. Check your drive firmware release notes though to make sure there's no tapealert issues in the rev you're running. There was a fix in 5.1MP4 to handle edge conditions that meant tapealerts could go unactioned. If you have IBM 3584's you need 5.1MP6 (IIRC, maybe MP5) for NBU to play nicely with library based cleaning (ie. graciously handle the situation when NBU wants to put a tape in the drive and there's a cleaning cart in there - prior releases could result in mount timeouts) Frequency based cleaning on SSO is a pain - you need to determine how much time was clocked on each media server in the SSO environment - NBU doesn't do this for you (in 4.x and 5.x minimally), you need to script it yourself if you cant use tapealert or library cleaning.

Library based cleaning can cause NB to down drives if it tries to mount a tape in a drive being cleaned by the robot. The robot doesn't tell NB that it's cleaning the drive, so NB thinks the resource is avail, discovers it's not, and downs the drive. If you have a "dirty" environment and enough drives do this, you could be faced with your backups not succeeding in their window. Of course, with Tape Alert (supported by pretty much all vendors) you do have to keep an eye on your cleaning tapes so that they don't run out and that is a manual process.

Re: [Veritas-bu] Drive Cleaning Frequency for SSO Drives
Actually, flip that around. Library based cleaning can cause NB to down drives if it tries to mount a tape in a drive being cleaned by the robot. The robot doesn't tell NB that it's cleaning the drive, so NB thinks the resource is avail, discovers it's not, and downs the drive. If you have a "dirty" environment and enough drives do this, you could be faced with your backups not succeeding in their window.

Frequency based cleaning is not supported on SSO drives. Preferred methods are in order of preference: 1. Library based cleaning 2.

[Veritas-bu] Drive Cleaning Frequency for SSO Drives
Is there a why to specify the cleaning frequency on SSO drives? The cleaning frequency setting under Device Monitor, accessed by right-clicking on the drive and selecting Drive Cleaning > Set Cleaning Frequency, is grayed out on all our SSO drives. Additionally there does not seem to be a way to change the attributes of the tape drive to specify a cleaning frequency from the Change Drive dialogue box for our SSO drives. What is the recommended procedure for setting drive cleaning frequency on SSO tape drives? Have the library perform this function? Or do we need to remove and re-add all out tape drives to specify the cleaning frequency when first added?
