Cause

T1000A/B/C/D This 377A error will occur if you try to read a block that was involved with a previous write perm. The 377A error description says "The read code was not making any progress."

FSC Dictionary Description:

(FSC Match Found in Rev. 3.62)

FSC: 377A RO_FSC_READ_HDWR_NOT_MAKING_PROGRESS

The read code was not making any progress while reading from tape.

Solution

Error 377A can occur if you try to read a block that was involved with a previous write perm.

As an aid to troubleshooting this type of problem, additional information was added to the drive event logs for the following code versions:

 - T10000C version RC362109 and higher.

 - T10000D version 4.10.10x and higher.

The internal Oracle tool used to process event logs will automatically look at this these fields and determine if the 377A is due to a previous write perm in this same location on the tape. A message will be placed into the SR if this is the case. Once you see this message you will want to copy the data off of this tape and take it out of service. Certify the tape to see if the write perm encountered on the tape was media related. If the certify job is successful it is ok to re-use the tape.

Note: in order to certify a tape do the following:

1) Copy all data off of the tape

2) Write the tape until it is full using any data. If this is successful then the tape is safe for re-use
