Operating Constraints
This section describes the operating constraints for ACS V8.8-1. An operating
constraint is a limitation placed on the operation of the controller. Other
constraints on host adapters or other system components may also apply. Keep
these constraints in mind to avoid problems and to help achieve the maximum
performance from your controller. Refer to the documentation that came with
your host server for more details.
Command Console LUN Usage
In order to avoid access conflicts between the sg and sd drivers, the Access
Device used for SWCC Agent communication must not be an sd device. Ensure
that the sg device used does not have an sd device mapped to the same LUN. The
best way to verify this is to use scsi_info on the sg device to verify that its Target
ID/LUN combination has a Logical Unit Number value of 0 (zero). With the array
controller operating in SCSI-3 mode, the CCLs are always mapped to Logical
Unit Number 0.
