Status Description Solution
offline (snap reserve
met)
Volume or snapshot was automatically set
oine due to the selected snapshot recovery
policy.
Increase the amount of reserved snapshot
space.
offline (thin max
grow met)
A thin-provisioned volume and its snapshots
were automatically set oine because a write
exceeded the maximum in-use space value.
Increase the value of the maximum in-use space
setting or increase the volume’s reported size.
offline (missing
pages)
A volume or snapshot was set oine because
some volume data cannot be found. This
condition is serious.
Contact your PS Series support provider.
offline (nospace auto
grow)
The thin-provisioned volume and its snapshots
were set oine because not enough free pool
space existed for the volume reserve to increase
automatically.
Increase pool free space. For example, you can
add another member to the pool or move
volumes from the pool.
offline (member down)
Volume or snapshot was automatically set
oine because a member that contains volume
or snapshot data is unavailable.
Identify why the member is unavailable and
correct the problem.
offline (lost blocks)
Volume or snapshot was automatically set
oine because blocks were lost. Computers
cannot access the volume or snapshot. This
condition is serious.
Click the status link and select how to manage
the lost blocks.
unavailable due to
SyncRep
Volume or snapshot is unavailable because
SyncRep is confused, often due to a mismatch
between the state in the database and the
expected state.
Determine the reason for the issue and correct
the problem.
available (no new
connections)
During a failover, SyncRep is trying to determine
which volume should be active. Until then, no
new connections are allowed.
Wait for SyncRep for to determine which
volume is active.
unavailable due to
internal error
Volume or snapshot is unavailable due to an
unexpected error.
Contact Customer Support for assistance.
Volume and Snapshot Requested Status
Table 36. Volume and Snapshot Requested Status shows the possible values for the requested status for a volume or snapshot.
Table 36. Volume and Snapshot Requested Status
Status Description
online
Administrator set the volume or snapshot online.
offline
Administrator set the volume or snapshot oine. Computers cannot access an oine volume or
snapshot.
online (lost blocks)
Administrator set the volume or snapshot online despite lost blocks. Authorized computers can
access the volume or snapshot.
If an application tries to read a lost block, an error occurs. If the block is rewritten, no error occurs,
and the block no longer shows a status of lost.
