Installation guide

Connecting to a CI VMScluster 6-3
To install a system with a CIXCD adapter into an existing cluster, there
are mandatory steps. The first four steps apply to the VMScluster configu-
ration.
1. Ensure that the LINK module on the HSC has a Quiet Slot DELTA
Time of 10. If it does not, you must change it to 10 using a switch,
wire, or board replacement and switch, depending on the model of the
HSC. Check the HSC Installation Manual for details.
2. Set the Quiet Slot DELTA Time to 10 on all nodes installed on the
cluster. Every CI node must have Quiet Slot DELTA Time set to 10.
3. Check that the OpenVMS version running on all nodes is compatible
with the new version of OpenVMS being installed. This is done by
checking the OpenVMS versions against the Software Product De-
scription or the required OpenVMS version for your system.
4. Check the HSC microcode and LINK module against required ver-
sions in the Cluster Revision Matrix. Update the required version
level as needed.
5. Set the Quiet Slot DELTA time on the CIXCD to 10. Install a jumper
between pins E15 and E45 on the XMI backplane’s CIXCD segment.
You cannot leave a default configuration. You must change the Quiet
Slot DELTA Time to 10. The default configuration for a system without
jumpers installed is:
• CI Node Address = 0
• Quiet Slot DELTA Time = 7 (must be set to 10)
• Boot Time = 1500 seconds
• Normal CI Arbitration
• Normal Header systems in the cluster
• Cluster Size = 16
• Short ACK Timeout
CAUTION: Failure to follow these configuration rules may result in unre-
liable operation.
