P/N: 900-10004-00 REV 02 USER GUIDE, IOSAFE R4
12
At the furthest bottom is the status bar with the date button which doubles its duty as a clock and a
link to the Clock page. The status LEDs to the right gives a quick glimpse of the system device
status.
The statuses represent:
Not present
– No disk or device attached.
Normal
– Device in normal operating mode. If the LED is blinking, this disk is currently
re-syncing. During the re-sync process, the performance is temporarily in a “degraded”
mode and another disk failure in the volume will render it dead.
Warning or Dead
– The device has failed or requires attention.
Inactive spare
– This disk is a “hot spare” on standby. When a disk fails, this disk will
take over automatically.
Awaiting re-sync
– This disk is waiting to re-sync to the RAID volume.
Life support mode
– The volume has encountered multiple disk failures and is in the state
of being marked dead. However, the ioSafe R4 has blocked it from being marked dead in
the event that someone may have accidentally pulled out the wrong disk during runtime. If
the wrong disk was pulled out, shutdown the ioSafe R4 immediately, reconnect the disk,
and power-on the ioSafe R4. If you reconnect the disk during runtime, the ioSafe R4 will
mark it as a newly added disk and you will no longer be able to access the data on it.
Background task active
– A lengthy background task such as a system update is in
progress.
