Volume Troubleshooting
The volume state indicates the current condition of a volume. The
volume state appears in the state column of the grid and in the Volume
Properties window. When a volume is unhealthy, an alert icon appears on
the volume and the volume is listed in the Alert Monitor window.
Unhealthy states include:
• “Volume State: Started” on page 198
• “Volume State: Stopped” on page 198
• “Volume State: Uninitialized” on page 198
• “Volume State: Degraded” on page 198
• “Volume State: Unusable” on page 199
Volume State: Started
The volume is accessible and has no known problems. This is the normal
volume state. No user action is required.
Volume State: Stopped
The volume is disabled and is not available for use.
• To return the volume to a usable state, start the volume.
Volume State: Uninitialized
The volume is enabled, but is not initialized. If this state appears during
volume creation, no user action is necessary.
• To put the volume in a usable state, start the volume.
Volume State: Degraded
The RAID-5 volume is in a degraded mode. This usually occurs when one
or more subdisks are unavailable and read requests require data
reconstruction. An underlying disk may have failed completely or there
may be I/O errors on part of a disk. Alternatively, an underlying disk
may be disconnected.
