the controller module LEDs do indicate a normal operating state, refer to chapter 6, for troubleshooting information. Figure 114 Identifying the ACS Process SCSI Cables Replacing SCSI cables requires that the disk enclosure be shut down. Shutting down the enclosure will degrade the performance of the array during the replacement. When the replacement is completed and the disk enclosure is powered up, the array will perform a rebuild (since I/O has occurred to the array while the disk enclosure was powered off). Array performance will be reduced until the rebuild is complete To replace a SCSI cable, complete the following steps: 1. Open the disk enclosure front door. 2. Power the disk enclosure down by setting the power switch to off. CAUTION When replacing a SCSI cable, it must be disconnected from both the controller enclosure and the BCC module. Disconnect the cable from the controller enclosure first, then from the failed BCC. DO NOT disk connect the SCSI cable from the BCC first or errors may occur when the enclosure is powered on. 3. Remove the SCSI cable from the controller enclosure connector. 338 Controller Enclosure Modules
