3.1.2 Matrix Server RHEL4 Release Notes

PolyServe Matrix Server Release Notes 14

1735 Matrix Server does not shut down applications

When Matrix Server is shut down, it terminates processes that

have open files on PSFS filesystems. To avoid this problem, we

recommend that you stop applications that are using the

filesystem before you shut down Matrix Server.

5862 mxconfig should query for HBA when PowerPath is installed

When a Matrix Server installation includes PowerPath, you need

to edit the /etc/polyserve/fc_pcitable file manually to specify the

HBA in use on the server. (This procedure is described in the

PolyServe Knowledge Base article “HBA Driver Procedures.”)

The mxconfig utility should query for the HBA version and

then edit this file automatically.

7250 Failover can take too long

When the IBM RDAC software is being used, the time required

for failover is dependent on the RDAC software. If failover

times are too long, consult the RDAC PAL on MatrixLink for

tuning suggestions.

7519 Third-party MPIO software must discover devices

When third-party MPIO software such as EMC PowerPath or

IBM RDAC is used, the third-party MPIO software must

discover and present storage devices to the operating system

before Matrix Server is configured or started.

If Matrix Server is started and the third-party MPIO software

has not previously discovered the devices, Matrix Server will

make a “best effort” to discover them. In some cases, Matrix

Server will initiate a single reboot. Matrix Server will not start if

it cannot discover the devices. The administrator must then

determine why the MPIO devices have not been discovered and

resolve the issue.
