Explanation
The node does not have sufficient connectivity to
other nodes or quorum device to form a cluster. If a disaster has
occurred and the nodes at the other site cannot be recovered, then
it is possible to allow the nodes at the surviving site to form a
system using local storage.
User Response
Repair the fabric or quorum device to establish connectivity. As a last resort when
the nodes at the other site cannot be recovered, then it is possible to allow the nodes at the
surviving site to form a system using local site storage as described
below.
To avoid data
corruption ensure that all host servers that were previously accessing the system have had all
volumes un-mounted or have been rebooted. Ensure that the nodes at the other site are not
operational and are unable to form a system in the future.
After invoking this command a full
re-synchronization of all mirrored volumes will be performed when the other site is recovered. This
is likely to take many hours or days to complete.
Contact IBM support personnel if you are
unsure.
Warning: Before continuing confirm that you have taken the following actions
- failure to perform these actions can lead to data corruption that will be undetected by the system
but will affect host applications.
- All host servers that were previously accessing the system have had all volumes un-mounted or
have been rebooted.
- Ensure that the nodes at the other site are not operating as a system and actions have been
taken to prevent them from forming a system in the future.
After these actions have been taken the satask overridequorum can be used
to allow the nodes at the surviving site to form a system using local storage.
