Read errors (READERR)
Specifies the number of read errors that have been recorded for each media
volume in the media inventory. When the number of read errors exceeds the
value specified in the read error threshold for a volume's media class,
the volume should be replaced with a new volume. The read error threshold
value can be reviewed in the Work with Media Classes display. Read errors
are expressed in kilobytes per read error.
The following guidelines can be used to determine the Read error threshold
value for your media class. If a volume or cartridge exceeds the criteria,
copy the contents to a new volume and discard the old volume.
3570
One temporary read error per 1000 megabytes read.
3580
One temporary read error per 10 gigabytes read.
3590
One temporary read error per 10 gigabytes read.
3480 and 3490
One temporary read error per 50,000,000 KB read.
1/4-Inch cartridge (6341, 6346, 6366 and 9346 and 6342 and 6347 at 10,000
bpi density)
One temporary read error per 12,500 KB read.
1/4-Inch Cartridge (6342 and 6347 at 16,000 bpi density)
One temporary read error per 4,170 read.
8-Millimeter cartridges (7208)
One temporary read error per 100 KB read.
1/2-inch volume reel (9347)
One temporary read error per 50,000 KB read.
1/2-inch tape reel (9348 and 2440)
One temporary read error per 100,000 KB read.
1/2-inch tape reel (3422)
One temporary read error per 144,000 KB read.
If all volumes used in a single drive exceed these criteria, the
read/write heads are probably dirty. You should also discard tape reels
and tape cartridges with a hard read error.
0
Initializes the read errors as zero.
read-errors
Specify a number of read errors.
Write errors (WRTERR)
Specifies the number of write errors that have been recorded for each
media volume in the media inventory. When the number of write errors
exceeds the value specified in the write error threshold for a volume's
media class, the volume should be replaced with a new volume. The write
error threshold value can be reviewed in the Work with Media Classes
display. Write errors are expressed in kilobytes per write error.
The following guidelines can be used to determine the Write error
threshold value for your media class. If a volume or cartridge exceeds the
criteria, copy the contents to a new volume and discard the old volume.
3570
One temporary write error per 250 GB written.
3580
One temporary write error per 10 GB written.
3590
One temporary write error per 1 GB written.
3480 and 3490
One temporary write error per 12,500 KB written.
1/4-Inch Cartridge (6341, 6346, 6366 and 9346 and 6342 and 6347 at 10,000
bpi density)
One temporary write error per 1,250 KB written.
1/4-Inch Cartridge (6342 and 6347 at 16,000 bpi density)
One temporary write error per 890 KB written.
8-Millimeter cartridges (7208)
One temporary write error per 50 KB written.
1/2-inch tape reel (9347)
One temporary write error per 4,500 KB written.
1/2-inch tape reel (9348 and 2440)
One temporary write error per 5,000 KB written for 1600 bpi. One temporary
write error per 8,500 KB written for 6250 bpi.
1/2-inch tape reel (3422)
One temporary write error per 8,500 KB written.
If all tapes used in a single drive exceed these criteria, the read/write
heads are probably dirty. You should also discard volumes and tape
cartridges with a hard write error.
0
Initializes the write errors as zero.
write-errors
Specify a number of write errors.
