UCS boot from EMC VNX

dynamoxxx — Fri, 01 Mar 2019 19:24:39 GMT

Hello folks,

I am booting a couple of UCS servers (Redhat) from EMC VNX. Everything seems to be working fine, i can remove zones on one fabric, i can remove all zones to SPA or all zones to SPB ...PowerPath is doing its thing and the system keep running. The other day we did VNX firmware upgrade and both servers panic and rebooted each time SPA or SPB got rebooted. Any idea what could be wrong, boot profile config attached.

Thank you

It isn't the boot profile issue, The server only looks that for trying to figure out where to boot from SAN. I'm not sure if it is multipath driver config or zone issuing or maybe an OS config?

EMC looked at host emcgrab file and did not see any issues with OS config nor multipathing (PowerPath). They are blaming Oracle RAC ..riiiiight.
