En détaillant, on peut remarquer que le disque 'hdisk19' est un disque de heartBeat PowerHA.
Pour éviter ce message, sans conséquence sur la production, il est possible de baisser le niveau de détection de panne dans les paramètres réseau du "network" lié au Heartbeat( En général 'diskhb')
Pour, on se rend dans les menus SMIT de Powerha :
# smit hacmp
Extended Configuration + Extended Topology Configuration +Configure HACMP Network Modules +Change a Network Module using Pre-defined Values
Puis, modifier la valeur en rouge.
Network Module Name diskhb
Description Disk Heartbeat Serial protocol
Failure Detection Rate Slow

Description
NIM thread blocked
Probable Causes
A thread in a Topology Services Network Interface Module (NIM) process
was blocked
Topology Services NIM process cannot get timely access to CPU
User Causes
Excessive memory consumption is causing high memory contention
Excessive disk I/O is causing high memory contention
Recommended Actions
Examine I/O and memory activity on the system
Reduce load on the system
Tune virtual memory parameters
Call IBM Service if problem persists
Failure Causes
Excessive virtual memory activity prevents NIM from making progress
Excessive disk I/O traffic is interfering with paging I/O
Recommended Actions
Examine I/O and memory activity on the system
Reduce load on the system
Tune virtual memory parameters
Call IBM Service if problem persists
