I'm beginning to wonder if my tape device or tape is going bad.
AFter a backup run tar exists with error
tar tvzf /dev/nsa0 > t2
tar (child): read error on /dev/nsa0 : Input/output error
gzip: stdin: decompression OK, trailing garbage ignored
tar: Unexpected EOF on archive file
checking status of the tape gives me
mt status

Current Driver State: at rest.
---------------------------------
File Number: 1 Record Number: 0 Residual Count 8704
Now does ANY residual count indicate error? mt errstat gives me:
mt errstat
Last I/O Residual: 0
Last I/O Command: 08 01 00 00 14 00 00 00 00 00 00 00 00 00 00 00
Last I/O Sense:
F0 00 80 00 00 00 11 14 00 00 00 00 00 01 00 00
00 00 00 00 00 00 00 F6 1F 40 08 00 6F 63 00 00
Last Control Residual: 0
Last Control Command: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
Last Control Sense:
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
okay. what does it mean? Residual count is 8704. yet, i/o residual
and control residual is 0. my understanding of this is getting worse.
