Mirrored Disk States

The mirrored disk states are:
State Description
Online Indicates that a disk is available for use or is currently in use by the CE operating system.
As a mirror copy begins, a mirror copy target transitions from offline to online and remains online
when the mirror copy completes successfully. However, if the copy cannot complete successfully
because of some system-wide state change or because of a disk level state change, the disk state
transitions to offline or faulted.
Offline Indicates that a disk is not available for use by the CE operating system. A disk can be offline
because either:
• The disk is the target of a mirror copy that is pending (not started).
• The disk was not detected during system boot. Possible reasons include the disk was powered
off, failed, or was improperly defined using the Endurance Configuration Utility.
• The disk was detected during system boot, but a characteristic of the disk was invalid. Possible
reasons include: a corrupt or invalid partition table, a corrupt or invalid partition, or the disk
was the target of a mirror copy that previously failed to complete.
• The mirror copy target is too small for a given mirror copy source. In this case, the target disk
remains offline indefinitely and must be replaced by a larger disk.
Table 2-7 MIC Port State Display Lights
Description
This state occurs only on CE MIC ports. It indicates that, from
the IOP's perspective, no information about the state of this port
has been received. Normally the CE MIC firmware relays the
local port status to the IOP MICs. This does not occur, however,
until the CE MICs are powered on and able to establish
communication.
The MIC hardware has not sensed any fiber signals through the
fiber connector since the IOP or CE has booted.
