You can install disks in an array and replace failed disks without disrupting I/O operations. See the PS Series Hardware Maintenance manual for your array model for instructions for physically installing and removing disks.
It is important to note the following:
When installing disks in an array, there is a two-minute delay between the time you insert a disk and the time the disk is automatically configured into a RAID set. This time interval enables you to install multiple disks and configure all the disks simultaneously, which is more efficient than installing a single disk, configuring it, and then repeating the process.
For example, when you install a disk in an array, a timer starts. If no other disks are installed, the disk is configured after a delay of 2 minutes. If you install another disk before 2 minutes have elapsed, the timer is restarted.
Notes: If you install a disk during an ongoing RAID reconstruction or verification operation, the new disk will not be configured until the operation completes.
If you remove a disk from one array and then install the disk in a different array, you must clear the disk label before the disk can be automatically configured. Click the foreign disk link in the Disk Status window. (See Table 3: Disk Status.)
After installing a disk, check the status to ensure that the disk is either online or a spare, as shown in the Member Disks window (Figure 9: Member Disks - PS5000 Array ).
