IBM OS/2

Special Unit Parameters:

•/TAG: -- Sets the number (1-16) of tagged commands for all target devices on the host adapter. A value of one disables tagged queuing 16 is the maximum number allowed and 8 is the default value.

•/TAG:1 -- Disables tagged queuing for all target devices on a given host adapter. The driver maintains a maximum of 2 non-tagged commands per target inter- nally. The driver treats all target devices as non-tagged devices, and sends only one command at a time per target to the host adapter.

Example:

BASEDEV=AIC78U2.ADD /A:0 /TAG:8 will set the number of tagged commands for all target devices on the first host adapter to 8.
