Installing HP Fabric Clustering System

On-Line Addition and Replacement Operations (OL*)

On-Line Addition and Replacement (OL*) of HP Fabric adapters is supported on HP Fabric Clustering System version B.11.23.02 with a couple of limitations related to replacing an HCA, see below.

Replacing an HP Fabric Clustering System HCA

CAUTION Do Not use an Attention Button to REPLACE an HP Fabric HCA.

Do not use the Attention Button method of On-Line Addition and Replacement (OL*) to replace an existing HP Fabric Clustering System HCA, as the slot will not power off. Use the Command Line Interface, or Peripheral Device Tool graphical user interface (GUI) to replace an HP Fabric HCA. Refer to the Interface Card OL* Support Guide, available on http://www.docs.hp.com for details on using standard OL* features.

To replace an HCA using the command line, you must use option olrad -fas in this example:

$ /usr/bin/olrad [-f] -r slot_id

where slot_id is the Slot ID of the slot.

The -foption overrides the “data critical” errors returned by Critical Resource Analysis. It is important to note that olrad will not allow “critical” errors to be overridden and that olrad automatically overrides “warnings”.

Whether -fis specified or not, critical resource analysis routines are run before an OLA/R operation, to ensure that the current OLA/R operation does not interrupt the normal working of the system; in other words, to identify “critical” errors.

The “data critical” errors are typically not critical to the system, but they may be critical to the user. Hence, the user need to decide whether or not to use the -foption for overriding these types of errors.

HP Fabric HCAs can be added using the Attention Button feature.
