SET RECORD
Authorization
Privilege Class: F
Purpose
Use SET RECORD to set the recording mode for a device.
Operands
- ON
- OFF
- controls the intensive recording mode
for the device that you specify. You can specify intensive recording for only one device at a time.
If you do not enter SET RECORD OFF, intensive recording is automatically terminated after 10 error records have been accumulated for the device, or when you activate intensive recording for a different device.
- rdev
- identifies the real device involved.
- LIMIT nn
- specifies the value at which a recording is made. While intensive recording is active, an error record is made for the first and for every nnth qualifying I/O error from the specified device.
- BYTE nn
- BIT n
- the BYTE and BIT operands define the test condition in the sense bytes. You can test two bits using an AND or OR relationship. The range for BYTE is 0 through 31; the range for BIT is 0 through 7.
- AND
- OR
- is the logical operation that you want to perform on two bits of sense data.
