Compaq HSZ80 Array Controller ACS Version 8.3 Configuration and CLI Reference Guide
CAUTION: Selecting SCSI-3 mode enables multiple CCLs—one for each
target at LUN 0. If the hosts access the CCL simultaneously, unpredict-
able consequences can occur. In cases where the CCL can be accessed
through multiple paths and LUNs, systems administrators of each host
must not attempt to access the CCL simultaneously.
Troubleshooting with the CCL
Troubleshooting and maintaining the controller should not be done using the CCL.
Instead, run the utilities and exercisers with the local connection that uses the
maintenance port cable. See “Establishing a Local Connection to the Controller,”
page 2–26.
Adding Storage Units with the CCL
If you have not configured any units and have not yet enabled the CCL, you must
establish a local connection as described previously in “Establishing a Local
Connection to the Controller,” page 2–26. This local connection through the
maintenance port cable provides a means of enabling the CCL, so that you can
communicate either through SWCC or through a PC or terminal.
To start configuring storage units, you must first set target ID numbers. See “Setting
SCSI Target ID Numbers,” page 2–33.
