Add checks on multipath #1

Closed bolinches closed 6 years ago

bolinches commented 6 years ago

At least check for TMO settings that are common for all OS

bolinches commented 6 years ago

Has to be a very generic one as different storages have different settings

bolinches commented 6 years ago

Will check for 2145 only

bolinches commented 6 years ago

work on branch https://github.com/bolinches/HANA-TDI-healthcheck/tree/2145

bolinches commented 6 years ago

Limited version added to master on https://github.com/bolinches/HANA-TDI-healthcheck/commit/e39c0be443b30db192a1772faf01c5c2e6c7057b

Passing a --with-multipath after XFS

At this moment ONLY checks within defaults. Not yet in devices

I am leaning to leave it as an optional check as only 2145 is checked

Went for simple check at this time. Later MAYBE the deeper one as above
