Compaq HSZ80 manual Troubleshooting with the CCL, Adding Storage Units with the CCL

4–21

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.
