HP 3PAR OS 3.1.2 MU5 Release Notes

DescriptionItemIssue ID
Using CLI command controlport rst -l on a 10G iSCSI port
under heavy host I/O can lead to fatal PCI errors and a subsequent
node reboot.

There is a problem with the chunklet moving algorithm used in the
intra-node (tunenodech) phase of tunesys. This causes a high
tunesys should not be run with a
maxchunk value of more than 2
(default)
70792
chunklet move failure rate if the value of maxchunk (number of
chunklets that can be moved in parallel) is set to greater than 2
(default). It is recommended that the value of maxchunk is left at its
default for all tunesys runs.
In this guide the maximum supported RCIP latency (delay times) is
incorrect.

On FC ports with a large number of attached hosts, failover/failback
may not be sufficiently fast with the consequence that multipathing

messages may be seen in host logs. Host multipathing may temporarily
mark paths as failed but they are quickly re-instated.
This behavior has been observed on Linux hosts (Redhat and SLES11)
which have more stringent path validation algorithms. However, it is
conceivable that it could also be observed on other host types
depending on how heavily the interface is loaded.

This problem is a defect on the Solaris host. The Brocade switch has
a feature where it will consolidate events that happen in close

succession into a single RSCN. The FC subsystem on Solaris does notconfigurations involving a Brocade
switch handle this appropriately and therefore does not re-establish all the
paths as it should.
Impact: Assuming host multi-pathing is configured properly, if this
problem occurs the customer may lose some IO paths, resulting in
possible reduced performance until the failed paths are restored.
Failed paths can be restored via controlport rst.
Note that this problem only shows up with the combination of Brocade
switch and a Solaris 11 host.
A VV which is split between tiers by Adaptive Optimization may
incorrectly display RAID type and device type (SSD, FC, NL)
information for a secondary tier CPG.

This is a display issue and does not affect the primary tier CPG from
which new VV growth is taken.
Active volume removals will prevent periodic syncs starting for volumes
within the same volume family. An error message will be returned

indicating that the volume is locked. Once the removals have finished
the next periodic sync will succeed.
During an online upgrade periodic remote copy groups may stop

upgrade is completed (i.e. after the cli upgradesys –finish
command has been entered). There is no need to stop periodic groups
before the upgrade is carried out. Synchronous Remote Copy groups
are unaffected. I/O to volumes in remote copy groups is unaffected.
No manual intervention is required to Remote Copy groups or volumes
before, during or after the upgrade.
