Cautions for Using the WRITE BUFFER Command

CAUTION

Be sure to follow these cautions when issuing the WRITE

BUFFER command:

The WRITE BUFFER command allows you to load new

microcode from the SCSI bus into the CTS. It is not

intended to be used for testing CTS functionality

(that is, do not issue this command unless you are actually

loading new microcode).

Do not load microcode from one model of CTS into

another. (For example, do not load microcode from an

EXB-8505 into an EXB-8205 or from an EXB-8505XL into

an EXB-8505.)

Be sure that the CTS is reserved for the initiator’s

exclusive use while the WRITE BUFFER command is

executing.

The CTS must be allowed to disconnect from the SCSI bus

during the WRITE BUFFER operation. (Set the DiscPriv

bit to 1 in the Identify message.)

Do not send other SCSI commands, such as TEST UNIT

READY, to the CTS while the WRITE BUFFER

command is executing.

Do not power off or reset the CTS while this

command is executing.

If a reset, hardware failure, or power failure occurs during

the execution of this command, the CTS may not be able to

operate. If this occurs, you can use the CTS Monitor

program to reload microcode (from a *.BIN file) through a

serial cable attached to the CTS’s Monitor port. (See the

documentation for CTS Monitor for complete instructions.)

Note: If there is a tape in the CTS, it will be unloaded and ejected.
