3.5.1 Matrix Server Release Notes

PolyServe Release Notes 27

7435 QLogic Switch login can cause Matrix Server failures

Matrix Server will not start if you are logged into a QLogic

FibreChannel switch and “admin start” is set. A message such

as the following will appear:

Switch address is not responding to SNMP SET requests.

Verify the configured community string has SNMP write

privileges.

The FibreChannel switches are not responding to SNMP requests.

Verify that the switches are configured to accept SNMP access

from this server using the configured community string. The

FibreChannel switches and Matrix Server must be configured

with the same community string.

If you log into the switch with “admin start” while Matrix

Server is running, this switch problem can affect fencing

operations and may cause the matrix to hang.

Workaround. Avoid putting the switch into “admin start” mode

while Matrix Server is running. If it is necessary to use this

mode while Matrix Server is running, limit the use of the mode

as much as possible.

8346 Partition tables can be constructed incorrectly

When partitioning a disk, make sure the first partition begins at

an offset beyond sector one on the disk. This is necessary

because the Linux kernel supports a number of different

partition table formats, and some of them make use of sector

one in addition to sector zero. If sector one is a data sector in a

partition, it is possible that user data written to that sector may

subsequently cause the Linux kernel to “recognize” a different

partition table format than is actually there, which could result

in the partitions being “constructed” incorrectly by the kernel.
