Kalau I/O VM-nya tinggi sebaiknya jangan diganti, dikosongkan dulu ESXi hostnya misalnya.
Gantinya via GUI karena kalau dari CLI nanti settingsnya balik lagi ke asal setelah ESXinya direstart
Kalau gantinya ke fixed dan pathnya sedang dipakai biasanya aman.
Ada notes jg di sini:
Changing the default pathing policy for new/existing LUNs (1017760) | VMware KB
Warning: Changing the default pathing policy for a specific SATP when there are multiple storage arrays using the same plug-in can cause other issues, such as incorrect pathing policies and unexpected storage failover results.
beberapa thread jg menyebutkan tidak ada downtime
change path selection policy from fixed path to round robin
