DescriptionItemBug ID

After a read-write virtual copy is admitted to a remote copy

group, following the initial synchronization, we read the data

Remote copy - initial synchronization

from a read-write virtual copy may

leave the secondary volume inconsistent

from the read-write virtual copy instead of synchronized virtual

copy. Therefore, the newly written data to the read-write virtual

copy is incorrectly replicated to the target side. The following

resynchronization rectifies the issue. The problem with the initial

synchronization is now addressed.

In 3.1.1, Tunesys assumed that node IDs always start from zero

and are contiguous. This can result intra-node tunes (tunenodech

tasks) not being generated for customer systems where the node

IDs are not numbered sequentially from zero. This issue is

addressed now.

Limitations of the InForm OS

Unsupported Remote Copy Across InForm OS Levels

Remote Copy is only supported between adjacent HP 3PAR InForm OS release levels. HP 3PAR

Storage System running InForm OS 2.2.4.nnn may not be in a Remote Copy configuration with a

Storage System running InForm OS 3.1.1 MU2.

No3.1.1.nnn2.2.4.nnn

Upgrades direct from all levels of InForm OS 2.2.4 to 3.1.1 MU2 when remote copy is configured

will fail. This includes offline upgrades and when remote copy is simply stopped. For these upgrades,

you must first upgrade to InForm OS 2.3.1 MU5, then proceed to upgrade to 3.1.1 MU2.

Known Issues with the InForm OS

System Manager Failover During Group Snapshot Creation May Result in an

Inconsistent Group (57883)

If System Manager failover occurs during group snapshot creation then the snapshot group may

not be consistent and some snapshots may be missing.

Workaround: If System Manager failover occurs during group snapshot creation then the group

should be removed and a new snapshot group created.

RCFC Link Issues When ISLs Are Removed (60936)

Under heavy remote copy traffic, adding or removing an ISL to the fabric may cause traffic delays

and congestion due to the dropping of FC frames.

Workaround: FC fabrics with multiple ISL connections should be configured with these links trunked

together.

Multiple Large importvv Operations May Cause a Slowdown of Tune and Import

Operations (62592)

If too many importvv operations are running or scheduled, a slowdown may be experienced on

all tune and import operations.
