V-5-0-237
VxVM vxio WARNING V-5-0-237 object subdisk detached from RAID-5 volume
at column column offset offset
■ Description: A subdisk was detached from a RAID-5 volume because of the failure
of a disk or an uncorrectable error occurring on that disk.
■ Action: Check for other console error messages indicating the cause of the failure.
Replace a failed disk as soon as possible.
V-5-0-243
VxVM vxio WARNING V-5-0-243 Overlapping mirror plex detached from
volume volume
■ Description: An error has occurred on the last complete plex in a mirrored volume.
Any sparse mirrors that map the failing region are detached so that they cannot be
accessed to satisfy that failed region inconsistently.
■ Action: The message indicates that some data in the failing region may no longer be
stored redundantly.
V-5-0-244
VxVM vxdmp NOTICE V-5-0-244 Path failure on major/minor
■ Description: A path under the control of the DMP driver failed. The device major
and minor numbers of the failed device is supplied in the message.
■ Action: None.
V-5-0-249
VxVM vxio WARNING V-5-0-249 RAID-5 volume entering degraded mode
operation
■ Description: An uncorrectable error has forced a subdisk to detach. At this point, not
all data disks exist to provide the data upon request. Instead, parity regions are used
to regenerate the data for each stripe in the array. Consequently, access takes longer
and involves reading from all drives in the stripe.
■ Action: Check for other console error messages that indicate the cause of the failure.
Replace any failed disks as soon as possible.
