Diagnosing and Resolving Shared Disk Problems A-7 3. Verify that all firmware versions, including those for the system ROM on each server, the host adapter firmware, and array controller firmware, are correct and consistent across all nodes. NOTE: Refer to the Compaq Parallel Database Cluster Model PDC/O5000 Certification Matrix for Windows 2000 for information about supported software and firmware versions for this PDC, at www.compaq.com/solutions/enterprise/ha-pdc.html Perform Cluster Hardware Checks Validate the cluster hardware by performing these steps: 1. Determine whether or not hardware errors or communications transport failures might be causing the problem. Use the Event Viewer to verify that no hardware errors or transport problems exist. Check the event log for disk I/O error messages or indications of problems with the communications transport. 2. Determine whether or not the Compaq servers support the physical SCSI disks that are installed in the MA8000/EMA12000 Storage Subsystems. Check the event log for disk I/O error messages or indications of problems with the communications transport. 3. Verify that the indicator lights on the host adapters, Fibre Channel SAN Switches or Storage Hubs, and array controllers all indicate working status. 4. Verify that the Gigabit Interface Converter-Shortwave (GBIC-SW) modules are all the correct brand or model type and are properly seated in the host adapters, Fibre Channel SAN Switches or Storage Hubs, and array controllers. 5. Inspect all Fibre Channel cables to verify that they are in good condition and have no breaks or excessive bends. 6. Verify that the Fibre Channel cables are properly installed and connected to the host adapters, Fibre Channel SAN Switches or Storage Hubs, and array controllers. For details on how to connect the GBIC-SW modules and the Fibre Channel cables, refer to the documentation provided with these hardware products. 7. Verify that all host adapters, array controllers, and shared disk drive modules are properly installed and seated in their receptacles.

Diagnosing and Resolving Shared Disk Problems
A-7
3.
Verify that all firmware versions, including those for the system ROM
on each server, the host adapter firmware, and array controller firmware,
are correct and consistent across all nodes.
NOTE:
Refer to the
Compaq Parallel Database Cluster Model PDC/O5000 Certification
Matrix for Windows 2000
for information about supported software and firmware versions
for this PDC, at

Perform Cluster Hardware Checks
Validate the cluster hardware by performing these steps:
1.
Determine whether or not hardware errors or communications transport
failures might be causing the problem. Use the Event Viewer to verify
that no hardware errors or transport problems exist. Check the event log
for disk I/O error messages or indications of problems with the
communications transport.
2.
Determine whether or not the Compaq servers support the physical
SCSI disks that are installed in the MA8000/EMA12000 Storage
Subsystems. Check the event log for disk I/O error messages or
indications of problems with the communications transport.
3.
Verify that the indicator lights on the host adapters, Fibre Channel SAN
Switches or Storage Hubs, and array controllers all indicate working
status.
4.
Verify that the Gigabit Interface Converter-Shortwave (GBIC-SW)
modules are all the correct brand or model type and are properly seated
in the host adapters, Fibre Channel SAN Switches or Storage Hubs, and
array controllers.
5.
Inspect all Fibre Channel cables to verify that they are in good condition
and have no breaks or excessive bends.
6.
Verify that the Fibre Channel cables are properly installed and
connected to the host adapters, Fibre Channel SAN Switches or Storage
Hubs, and array controllers. For details on how to connect the
GBIC-SW modules and the Fibre Channel cables, refer to the
documentation provided with these hardware products.
7.
Verify that all host adapters, array controllers, and shared disk drive
modules are properly installed and seated in their receptacles.
