8.3.5 Overview of Performing InfiniBand Network Fabric Switch Updates

Patchmgr manages the update orchestration in a rolling manner for InfiniBand Network Fabric switches

Note:

Perform storage server updates separately from RDMA Network Fabric switch updates. Do not update storage servers and RDMA Network Fabric switches concurrently. RDMA Network Fabric network connections must be stable during some critical stages of storage server updates. The RDMA Network Fabric switch firmware upgrade requires a switch reboot, which disrupts some connections on the RDMA Network Fabric.

The general steps for using patchmgr are:

1. Download the target Exadata software from My Oracle Support and stage it on the driving system. See My Oracle Support document 888828.1.

2. Create the component_list_file containing the list of InfiniBand Network Fabric switches to update.

3. Configure SSH equivalence from the user that will run patchmgr to root on all InfiniBand Network Fabric switches in the component_list_file.

4. Run patchmgr prerequisite check and correct any issues.

5. Run patchmgr to update InfiniBand Network Fabric switches. InfiniBand Network Fabric switches are always updated in a rolling manner.
