Description Workaround/Resolution
MDT-152854
Connectivity -
Hosts
Running an unmap operation might cause
a host I/O latency impact of more than
15%. You can disable auto-unmap for
applications that have this feature, or
manually schedule an unmap operation to
reduce the impact on hosts.
Disable auto-unmap for applications that
have this feature. Schedule unmap
operations manually to reduce the impact
on hosts.

Connectivity -
Hosts
When you add a host, in rare cases, you
may not see any active sessions or
connected paths for the initiators for up
to 10 minutes on the Initiators tab.
Do not try adding the host again. Wait for up
to 10 minutes for the active sessions to
appear.

Xcopy operations can impact host I/O
performance.

MDT-171399
Connectivity-
Networks
The PowerStore Network Configuration for
Delll PowerSwitch Series Guide provides
examples with the flowcontrol receive set
to on. However, it is recommended to set
flowcontrol receive off and flowcontrol
transmit off for best performance.
Do not follow the flowcontrol settings from
the examples in the PowerStore Network
Configuration for Delll PowerSwitch Series
Guide rather reference the PowerStore Host
Configuration Guide for the correct
flowcontrol settings.
MDT-168926
Connectivity-
Networks
A cluster "Network validation failed with
unexpected error (0xE0E700001)"
message is returned erroniously while
validating initial configuration. The error
occurs because an internal entry for DNS
was previously configured.
Ignore the warning and continue configuring
the cluster. After the cluster is created you
can validate that the DNS configuration was
succesful in the PowerStore Manager.
MDT-55667 Data Collection
Storage container capacity metrics are not
available until I/O operations have begun.
Look at the capacity metrics again after I/O
operations on the storage container have
been performed.
MDT-133408 Data Protection
When a volume group is created with
member volumes and is protected by a
protection policy that includes a
replication rule, the volume group
members may be delayed in being
replicated to the remote system until the
next RPO cycle. The default replication
rule RPO value in PowerStore Manager is
1 hour, but it can range from 5 minutes to
24 hours.
If the remote system connection is healthy,
the member volumes should automatically
be replicated to the destination during the
next RPO cycle. To update the member
volumes on the destination before the next
RPO cycle, navigate to Protection->
Replication, select the volume group session
and perform a "Synchronize" operation.
