condition where one of the Windows hosts
is isolated from both its peer and its
quorum witness.
SCOS-17981 Live Volume and
Replication
Server mappings may not be removed
completely when a server is removed from
a cluster using Storage Manager before the
server is removed from the cluster.
When a server is removed from one
Storage Center only, or a volume is
unmapped on one Storage Center only,
the persistent reservations might not stay
consistent between primary volume and
secondary volume.
Remove the server from the cluster
through the operating system first. After
the server is rebooted, remove the server
object using Storage Manager.
When removing a server from a cluster or
unmapping a volume, perform the following
steps:
1. Remove the server from the cluster, or
unmap the volume on the server side
before making changes on the Storage
Centers.
2. Delete the server on both Storage
Centers, or unmap the volume on both
Storage Centers.

Replication

SCOS-22026 Storage
Management
Removing an HBA or deleting a server
object before unmapping it from volumes

from completing properly.
Contact technical support.

Management
In rare instances, SC7020 updates do not
complete successfully and the Storage
Center might indicate that updates are still
required.
Contact technical support.
