Oracle^® ZFS Storage Appliance Customer Service Manual

MFR/MODEL

The disk shelf manufacturer and the model number.

Type

Device type HDD or SSD.

RPM

Revolutions per minute; the speed of the disk drive.

Data

Total size of all data disks within the disk shelf.

Cache

Total size of all read-optimized cache devices within the drive shelf. If there are no cache devices within the shelf, then "-" is displayed.

Read cache devices are supported in DE2 disk shelves with a minimum software version. For software requirements and slot configuration rules, see Disk Shelf Configurations.

Log

Total size of all write-optimized cache devices within the drive shelf. If there are no log devices within the shelf, then "-" is displayed.

Paths

Total number of I/O paths to the disk shelf. The only supported configurations are those with multiple paths to all disks, so this should read "2" under normal operating circumstances. Clicking the information icon will bring up a dialog with information about each path. This includes which HBAs are connected to the disk shelf, and the state of any paths. If the disks within the disk shelf are not currently configured as part of a storage pool, complete path information will not be available, though it displays two paths to the chassis.

Locate

Toggle the locator LED for this disk shelf. If the LED is currently on, then this indicator will flash.
