Symptoms

590F and 5911 (and other) reel motor permanent errors on T10000C or T10000D tape drives.

Cause

Reel motor failures related to the encoder. (tach disk)

Solution

T10000A and T10000B Drives:

590F and 5911 errors can occur on T10000A and T10000B drives if the encoder signal becomes erratic. The drive should be replaced for any 590F or 5911 errors on T10000A and T10000B drives.

T10000C and T10000D drives:

Beginning with firmware version 1.61.301 For T10000C and 4.08.105 for T10000D, servo code was introduced that allows for improved handling of tape after receiving a reel motor encoder issue. If a T10KC or T10KD drive running with these code versions (or later) encounters either a 590F or 5911 error it will do a slow unload of the tape. These errors may or may not be seen in the library log but may be seen as a check condition on the drive display in VOP. (e.g. CHK 590F) Check the drive display using SLC or look at the tape drive event log if this error is suspected. If a T10KC or T10KD drive running with the above listed code versions encounters a 590F or 5911 FSC (or the other related reel motor FSCs) it will cause a permanent error to be posted for every tape loaded thereafter. Prior to 3.64.101 code the following applies: if the drive detects one of these 5 conditions (5919, 591A, 591B, 591C, 5C62) it will SNO the drive.

The following note is in the 3.64.101 release notes for T10000C tape drives however 3.64.101 code was pulled back. This same change will be in future 3.65.103 microcode for T10KC drives.:

Service requested engineering for a new code change to down drives for these four FSC’s related to reel motor failures that have been known to expose the customers tape to potential physical damage. These four FSC’s are 590F, 5911, 550C and 550D. One time failures will now prevent any/all subsequent load requests and the drive must be replaced and returned through service repair.

A similar note was applied to released 4.13.101 microcode for T10000D drives.

The drive must be replaced if any of these reel motor encoder type error conditions are seen.
