I guess, obviously the fail over to the secondary node will fail as the cluster services won't be able to access the new disks. In this scenario, will it be ok to create the PVIDs for the new disks on the secondary node and then subsequently fail over to the secondary node?
You are right both with your assumption about what whould happen and that you need to make the PVIDs known to secondary before you could proceed. I don't know which HACMP version you use. Regardless of the version the following procedure should work: make the PVID visible, then update the VG information on secondary while HACMP is stopped (by a Learning Import), then verify and sychcronise the Cluster.

If you are curious you could try to verify/sync the cluster with the autocorrection flag activated after assigning the PVID but before the manual import to find out if there was a chance that the cluster would resolve the problem on its own. I did not try this with current HACMP version but saw some enhancements in 5.4.1 compared to earlier versions that make me think that it might be possible now. When you are below version 5.3 forget it.

addnode(8)						      System Manager's Manual							addnode(8)

Name
       addnode - add or change an entry in the nodes database

Syntax
       /etc/addnode node [ options ]

Description
       The  command adds a new node entry to the nodes database or modifies an existing entry.	The nodes database is the one used by DECnet.  The
       command defines the information that is necessary for your ULTRIX node to be capable of down-line loading and up-line dumping a	particular
       target  node.  The node address is the address of the target node.  If the target node is a DECnet node, then the node address is mandatory
       and the node name is optional.  However, if the target node is a non-DECnet node, for example, a terminal server, you should  specify  only
       the node name and omit the node address.

       If you do not specify an absolute pathname for secondary load, tertiary load, system load, diagnostic load, or dump file, the default path,
       is used during the load or dump process.

       A node address is a decimal integer in the range of 1 to 1023 for single area networks, or has the format a.n for multiarea networks, where
       a  is  the network area number (a decimal integer in the range of 1 to 63) and n is the node number (a decimal integer in the range of 1 to
       1023).

       The node name is the node name of the target node.

       If the target node is a DECnet node, the node name is optional.	However, if the target node is a non-DECnet node, for example, a  terminal
       server, the node name is mandatory (and the node address should be ignored).

       A node name can be from 1 to 6 alphanumeric characters, including at least 1 alphabetic character.

Options
       -A   Uses the specified host address (next argument) as that of the target node.

       -D   Creates an up-line memory dump of the target node in the specified file (next argument).

       -N   Uses the specified name (next argument) as that of the target node.

       -c   Uses the specified service and device number (UBA-n or QNA-n) as the circuit to the target node.

       -d   Sends the specified diagnostic load image (next argument) to the target node.

       -h   Uses the specified address (next argument) as the Ethernet address of the target node.

       -l   Sends the specified system load image (next argument) to the target node.

       -p   Uses the specified service and password (next arguments) in accessing the target node.

       -s   Sends the specified secondary load file (next argument) to the target node.

       -t   Sends the specified tertiary load file (next argument) to the target node.

Examples
       % /etc/addnode mynode -h aa-00-03-00-01-19  <RET>
       -s /usr/download/secondary  <RET>
       -t /usr/download/tertiary  <RET>
       -l system <RET>

       This command adds the non-DECnet, node mynode, to the nodes database, which has the Ethernet physical address aa-00-03-00-01-19.  This com-
       mand also specifies the file names for the secondary loader, the tertiary loader, and the system loader.  Note that  a  path  name  is  not
       specified for the system loader; consequently, the loader uses the default path when searching for that file.
       # /etc/addnode 44.71 -h aa-00-03-00-01-20 <RET>

       This command adds the DECnet node 44.71 to the nodes database, which has the Ethernet physical address aa-00-03-00-01-20.
