Prepare an Exalogic Infiniband (IB) Fabric, for any planned outage of an Infiniband Switch within that IB Fabric during Switch replacement.
The checklist in this Note will assist Customer-admin to determine if a full Fabric outage will be required, based on the results of checks done.
The scope of this document is EXALOGIC platform ONLY. All other platforms refer to following MOS Note:
<Note 2140928.1>: How to Prepare an Infiniband (IB) Fabric for Planned Outage of an IB Switch
Planned Outage could include a Reboot (or boot after previous shut-down), Patching (firmware-upgrade), or Replacement of an IB Switch in the IB Fabric.
The checks and actions in this document are critical to ensuring that production traffic in the Exalogic’s Infiniband (IB) Fabric may be resilient to the necessary restart of the IB Switch involved in any of the above operations.
Based on the result of the aforementioned checks, guidance is provided - via a checklist - as to whether a full downtime of the IB Fabric will be required (full outage of all switches and nodes actively participating in the fabric). Customers should only take the IB Switch outage within a production IB Fabric, when all checks are cleared in the affirmative.
