Vaisala IRIS - Unmounting a Tape or Disk

Issuing a Stop command during a Record or Retrieve operation does not damage any files.
The Stop command has dierent eects depending on the operation being stopped:
During Record
Stop allows the file currently being written to be completed.
If Record is re-issued, IRIS resumes recording at the end of the last file.
During Retrieve
Stop finishes retrieving the last file, then stops retrieving.
If Retrieve is re-issued, the retrieve process continues where it left o.
During Inventory
Stop causes the inventory to halt. The resulting log is incomplete and the filter
summary shows Incomplete Log.
Retrieve operations that are limited to the part of the log that was completed can still
be done. If the Inventory command is reissued, the inventory is started from the
beginning of the tape.
During Mount
Stop cancels the Mount operation and rewinds the tape.
During Unmount
Stop has no eect.
8.9 Unmounting a Tape or Disk
The Unmount command causes IRIS to rewind a tape and take the tape or optical disk drive
o line. The log information is cleared from the screen. This command must be invoked
before a new tape can be mounted.
1. Select Commands > Unmount.
2. Wait for the tape to completely rewind, then remove it from the tape drive.
If the media is a DVD, the contents of the temporary buer used for writing the DVD are
flushed to the DVD, that is, you do not lose the data in the buer.
This may delay the unmounting step by 20 seconds. If you quit IRIS (qiris) without
unmounting the DVD, the buer is flushed in the same way (delaying the qiris).
