ASM diskping time

Hello

My customer found following issues after changing a fiber between storage and fiber switch.

1. half of the disk were dismounted and did not return to mount status after the fiber was changed

2. CRS was also abnormal, CRS-0184: Cannot communicate with the CRS daemon.

3. DB instance are ok, Weblogic and applications are ok too

Here is my question:

Is there any parameter to set for the timeout of diskping of ASM, after the timeout, ASM disk will be dismounted.

the recovery time of multi-path is 60s

Environment:

DB: 11.2.0.3.9

OS:linux

storage is HDS VSP

multi-path software is HDLM 7.6

Best Regards
