Using a Microcode Update Tape
When a microcode update tape is inserted into the CTS, the CTS
automatically detects its presence and upgrades the microcode to the
new level. No operator intervention is needed.
To use a microcode update tape, follow these steps:
1.
Disconnect the CTS from the SCSI bus by unplugging the SCSI
connector.
Important
If the location of the CTS makes removing the cable
inconvenient, ensure that a SCSI bus reset cannot occur
during microcode update process.
2.
Apply power to the CTS and wait for it to complete its power-on
self-test.
3.
Insert the microcode update tape in the CTS.
Steps that occur during the microcode update process
The following steps occur automatically when you insert a microcode
update tape in the CTS.
1.
The CTS loads the tape, reads the digital LBOT pattern, and
identifies it as a microcode update tape. The bottom green LED
will begin to flash. (The rate of flashing varies between slow and
fast as the CTS switches between normal-speed and high-speed
tape operations.)
2.
The CTS reads the data on the tape into its buffer. The top amber
LED will begin to flash slowly (about 1 blink per second), and
the bottom LED will continue to flash.
3.
The microcode load image in the buffer is validated. This step
ensures that the microcode to be loaded into the CTS is valid.
