Administrator Guide

NOTE: Setting a volume with lost blocks online is a data integrity risk. The blocks might contain old or invalid data.
To manage a volume or snapshot with lost blocks:
1. Click Volumes.
2. Expand Volumes and then select the volume name.
3. Click the Status tab.
4. Click oine-lost-cached-blocks.
5. Either:
• Click Set the volume online but retain the lost blocks to set the volume or snapshot online but keep the lost blocks. The
volume (or snapshot) status changes to online-lost-blocks.
• Click Mark the lost blocks valid and set the volume online to set the lost block status to valid. The volume (or snapshot)
status changes to online. The status of the members containing volume data changes to online.
6. Click OK.

Administrator set the volume or snapshot online,
and no failures have occurred.
None needed; informational. Online volumes and
snapshots are shown in the far-left panel in
black text.

Administrator set the volume or snapshot
oine.
None needed; informational. Computers cannot

have occurred. Oine volumes and snapshots
are shown in the far-left panel in gray text.
offline (snap reserve
met)
Volume or snapshot was automatically set
oine 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 oine 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 oine 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 oine 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
oine 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
oine 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.
