Veritas Storage Foundation 5.1 SP1 Cluster File System Release Notes (5900-1509, April 2011)

Issues related to Symantec Product Authentication Service with VCS

This section covers the known issues related to Symantec Product Authentication

Service (AT) in this release.

Verification for VRTSat package or patch returns errors

If you run swverify command on VRTSat package or patch, the command returns

errors for missing files on VRTSat.CLIENT-PA32. [1244204]

Workaround: This message may be safely ignored.

Issues related to LLT

This section covers the known issues related to LLT in this release.

LLT port stats sometimes shows recvcnt larger than recvbytes

With each received packet, LLT increments the following variables:

■ recvcnt (increment by one for every packet)

■ recvbytes (increment by size of packet for every packet)

Both these variables are integers. With constant traffic, recvbytes hits and rolls

over MAX_INT quickly. This can cause the value of recvbytes to be less than the

value of recvcnt. [1788315]

This does not impact the LLT functionality.

LLT may incorrectly declare port-level connection for nodes in

large cluster configurations

When ports get registered and unregistered frequently on the nodes of the cluster,

LLT may declare that a port-level connection exists with another peer node. This

occurs in some corner cases even though a port is not even registered on the peer

node. [1809827]

Issues related to I/O fencing

This section covers the known issues related to I/O fencing in this release.

All nodes in a sub-cluster panic if the node that races for I/O

fencing panics

At the time of a network partition the lowest node in each sub-cluster races for

the coordination points on behalf of that sub-cluster. If the lowest node is unable
