Table 16. virtual-volume field descriptions (continued)
Field Description
NOTE: If initialization is requested during the creation
of the virtual volume, you must wait until the
initialization process is completed successfully to use
the virtual volume. If the initialization process fails,
restart the process by using the virtual-volume re-
initialize command.
locality
● local - The virtual volume relies completely on storage at
its containing cluster.
● remote - The virtual volume is a proxy for a volume
whose storage resides at a different cluster. I/O to a
remote virtual volume travels between clusters.
● distributed - The virtual volume is the cluster-local
representation of a distributed RAID-1. Writes to a
distributed volume travels to all the clusters at which it
has storage; reads come, if possible, from the local leg.
operational status
● degraded - The virtual volume may have one or more
out-of-date devices that will eventually rebuild.
● error - One or more of the virtual volume's underlying
devices is hardware-dead.
● ok - The virtual volume is functioning normally.
● starting -The virtual volume is not yet ready.
● stressed - One or more of the virtual volume's
underlying devices is out-of-date and will never rebuild.
● unknown - Metro node cannot determine the virtual
volume's Operational state, or the state is invalid.
scsi-release-delay
A SCSI release delay time in milliseconds. Optimum value is 0
to 2 seconds. Setting a very high value could break the SCSI
semantics. If another reserve arrives at this cluster within this
time frame, neither release nor reserve will be sent across the
WAN.
service-status
The service status of a virtual-volume.
● running - I/O is running for the virtual-volume.
● inactive - The virtual-volume is part of an inactive
storage-view and is not visible from the host.
● unexported - The virtual-volume is unexported.
● suspended - I/O is suspended for the virtual-volume.
● cluster-unreachable - Cluster is unreachable at this
time.
● need-resume - Issue re-attach to resume after link has
returned.
storage-array-family
The family of the storage array from which the virtual volume
was created.
storage-tier
The storage-tier for the virtual volume.
supporting-device
The local, remote, or distributed device underlying this virtual
volume.
system-id
The internal system ID for the storage.
volume-type
Always virtual-volume.
vpd-id
The VPD identifier for the virtual volume.
