27.1 About This Command
The WRITE FILEMARKS command causes the CTS to write one or
more filemarks or setmarks (available in 8500c format only) to tape.
In 8500c, 8500, and 8200c formats, filemarks can be buffered.
Setmarks (8500c format only) can also be buffered. Each buffered
filemark or setmark uses 1 KByte of the CTS’s 1-MByte buffer. In 8200
format, filemarks cannot be buffered. When the CTS is writing data
in 8200 format, the WRITE FILEMARKS command causes the CTS to
write all data remaining in the buffer to tape and then to write the
requested number of filemarks.
27.2 Field Definitions
Byte 01, Bit 1 - WSmk (Write Setmark)
EXB-8505 The WSmk bit allows you to specify whether you want the EXB-8505
to write setmarks instead of filemarks at the current position, as
follows:
0 – Write filemarks at the current position
1 – Write setmarks at the current position
Note: Setmarks are supported for tapes written in 8500c format only.
If you set the WSmk bit to 1 and the tape is in 8500, 8200c, or
8200 format, the EXB-8505 returns Check Condition status.
The sense key is set to Illegal Request (5h), the ASC and ASCQ
are 30h and 02h, and the Fault Symptom Code is D7h.
For information about the differences between filemarks and
setmarks, refer to Chapter 3.
EXB-8205 Setmarks are not supported by the EXB-8205. The valid value for the
WSmk bit is 0. If you set the WSmk bit to 1, the EXB-8205 returns
Check Condition status. The sense key is set to Illegal Request (5h),
the ASC and ASCQ are 30h and 02h, and the Fault Symptom Code is
D7h.
