Fault detection is slower in case of Multipath I/O over Fibre Channel

Last published : Oct 01, 2026
If the storage is configured with Multipath I/O (MPIO) over Fibre Channel (FC), the storage framework takes more time to detect a storage failure and notify SFW. This results in a delay in the fault detection. (2245566)
Typically, fault detection takes 30 seconds or more without MPIO and up to a minute when MPIO is used over FC.
