Displaying the Disk Configuration

To display the status of a disk array, click:

Members > member_name > Disks tab

The Member Disks window appears, displaying the disks in the array. The output shown depends on your array model and the installed disk type (SAS or SATA). Figure 9: Member Disks - PS5000 Array shows the disks in a PS5000 array.

The Installed Disks panel shows detailed information about each disk, including the disk slot, type, model and revision, size, status, and errors.
