2. Identify the expanded disk array layout by performing the following tasks: a. Create a detailed diagram of the expanded HP FC60 array layout. Include all Fibre Channel and SCSI cabling connections. This diagram will serve as your configuration guide as you add the new enclosures. The Capacity Expansion Map on page 235 should assist you in identifying where disk will be moved in the new configuration. b. Attach a second label to each disk that is part of a LUN, identifying the disk enclosure and slot the disk will occupy in the new configuration. The disk should be moved to the enclosure and slot that corresponds to the original channel:ID of the disk. Step 2. Backup All Disk Array Data CAUTION It is critical that you perform this step. Protection of user data is essential if a problem occurs during the expansion process. 1. Stop all I/O activity to the disk array. 2. Backup all data on the Disk Array FC60. 3. Label and store the backup media in a safe place. Step 3. Prepare the Disk Array for Shut Down 1. Determine if any LUNs in the disk array are using a global hot spare as a result of a disk failure. If any hot spares are in use, perform the following steps: a. Identify and replace the failed disk that caused the use of the global hot spare. b. Wait for the disk array to complete the process of copying data from the hot spare to the replacement disk. c. Verify that the LUN is now in the OPTIMAL state. 2. Verify that the status of each LUN on the disk array is OPTIMAL. All LUNs must be in the optimal state before continuing. 226 Adding Disk Enclosures to Increase Capacity
