HP-UX Integrity Installation Overview & Planning
Install HP Fabric Clustering System Software
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 or newer with a couple of limitations related to replacing an HCA, see below.
Replacing an HCA
CAUTION
Do Not use an Attention Button to REPLACE an HP Fabric Clustering System 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 -f as in this example:
$ /usr/bin/olrad [-f] -r slot_id
where slot_id is the Slot ID of the slot.
The -f option 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 -f is 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 -f option for overriding these types of errors.
HCAs can be added using the Attention Button feature.
Install HP Fabric Clustering System Software
This section describes the steps necessary to install HP Fabric Clustering System software. The same
software version must be installed on each instance of the HP-UX operating system in the fabric. The AB345A
HCA can only be installed in supported Integrity servers.
Step 1. Log on to the system as root.
Step 2. Insert the software media into the appropriate drive. If the software is being loaded from a
CD-ROM, go to step 3; otherwise, go to step 4. The software can also be located at
http://www.software.hp.com.
Locating the HCA Software on software.hp.com (AB286A or AB345A)
The drivers, utilities and manpages for the AB345A HCA are on the HP-UX application release CD.
