Operating Systems AIX Cleaning tape frequence for DDS Post 302562715 by dukessd on Friday 7th of October 2011 07:52:48 PM

Cleaning tapes are a bit of rough tape that scrape the magnetic tape residue off of the working parts of the drive so if you over use them you will wear out the drive prematurely.

Most modern tape drives will let you know when they need cleaning.

If you use quality tapes and use the drive daily then about once a month should be fine for running the cleaner through it.

Always keep a cleaning tape for each drive / never use a cleaning tape in more than one drive.

Ideally the same applies for data tapes.

If you hope to restore a data tape on a different drive then check / test this works before you need to rely on it because there might be alignment differences between the drives meaning one drive will struggle reading a tape made on a different drive.

mahe sure the drive firmware is up to date.

Here is a useful tape doc for AIX:

NAME
tcopy - copy a magnetic tape SYNOPSIS
tcopy source [destination] DESCRIPTION
The tcopy utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the contents of a tape is that there are two tape marks at the end. When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files. If a des- tination is specified, tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro- duces the same output as it does when only scanning a tape. The tcopy utility requires the use of Berkeley-compatible device names. For example, example% tcopy /dev/rmt/1b /dev/rmt/2b ATTRIBUTES
