You can hot-add a disk shelf when you want to increase storage without any reduction in performance.
About this task
- This procedure is for hot-adding a disk shelf to the last disk shelf in a stack.
This procedure is written with the assumption that the last disk shelf in a stack is connected from IOM A to bridge A and from IOM B to bridge B.
- This is a nondisruptive procedure.
- You should hot-add an equal number of disk shelves at each site.
- If you are hot-adding more than one disk shelf, you must hot-add one disk shelf at a time.
Note: Each pair of FibreBridge 7500N or 7600N bridges can support up to four stacks.
Attention: Hot-adding a disk shelf requires you to update the disk drive firmware on the hot-added disk shelf by running the storage disk firmware update command in advanced mode. Running this command can be disruptive if the firmware on existing disk drives in your system is an older version.
Attention: If you insert a SAS cable into the wrong port, when you remove the cable from a SAS port, you must wait at least 120 seconds before plugging the cable into a different SAS port. If you fail to do so, the system will not recognize that the cable has been moved to another port.
