Changing hdisk device names is tedious. I'd reconfigure disk heartbeat devices.
If you want to change hdisk names you need to rmdev -dl them. You could use dummy disks to keep cfgmgr from taking certain hdisk names (hdisk12) and then delete the dummy and the former hdisk12 to make it become hdisk12 after another rmdev command. If you delete all of the hdisk devices cfgmgr should be forced to detect devices in a serial way but not in parallel (-S option) but even then the row in which the disks are being detected might be different if signal runtime is influenced by your FC network (especially if your storage is located in different data centers).
Either way you can damage your cluster.... which HACMP version do you use?

Hello,
On 4/20/2018, we performed a disk replacement on our IBM 8202 P7 server. After the disk was rebuilt, the SAS Disk Array sissas0 showed a status of degraded. However, the pdisks in the array all show a status of active.
We did see a message in errpt. DISK ARRAY PROTECTION SUSPENDED.

HEARTBEAT(8) System administration utilitie HEARTBEAT(8)
NAME
heartbeat - Heartbeat subsystem for High-Availability Linux
DESCRIPTION
heartbeat is a basic heartbeat subsystem for Linux-HA. It will run scripts at initialisation, and when machines go up or down. This version
will also perform IP address takeover using gratuitous ARPs. It works correctly for a 2-node configuration, and is extensible to larger
configurations.
It implements the following kinds of heartbeats:
o UDP/IP broadcast;
o UDP/IP multicast;
o UDP/IP unicast;
o Bidirectional Serial Rings ("raw" serial ports) -- this type is deprecated and should no longer be used;
o special "ping" heartbeats for routers, etc. -- this type has been superseded by functionality in pacemaker() and should no longer be
used.
Comprehensive documentation on heartbeat is available in the Heartbeat User's Guide. If this documentation is not installed on your system,
it can be found at http://linux-ha.org/.
OPTIONS
The following options are supported by heartbeat:
-d
Increment debugging level. Higher levels are more verbose.
-r
Reload heartbeat. This option is functionally identical to sending a running heartbeat process a HUP signal. If the configuration has
not changed, then this option is essentially a no-op. If ha.cf(5) or authkeys(5) has changed, then heartbeat will re-read these files
and update its configuration.
This option may not be used together with -R.
-k
Kill (stop) heartbeat.
-s
Report heartbeat status.
-R
Heartbeat restart exec flag (internal use only). May not be used with -r.
-C
Heartbeat current resource state for restart (internal use only). Only valid with -R.
-V
Print out heartbeat version.
Note that most of these options are used for supporting the heartbeat init script, which provides the conventional start, stop, status and
restart options (among others). It is recommended to use this rather than invoking the heartbeat command directly.
