How do I get completely rid of this LUN on a SD Card used for booting ESXi?

Hello.

Two of our Hosts have two LUNs on their SD Card and we suspect this blocks upgrade to ESXi 6.7U1.

How do I get completely rid of this LUN 1 (mpx.vmhba32:C0:T0:L1) on a SD Card used for booting ESXi?

Why do you suspect this is blocking your upgrade to 6.7? What evidence do you have that might suggest this?

Because I have 8 identical HW wise Hosts of which 6 only have one LUN on their SD Card and all 6 are now upgraded.

The remaining 2 have two LUNs on their SD Card and none of those two keeps the upgrade because bootbank get pointed to /tmp instead of the proper place and after a reboot of the host it reverts back to 6.5 and Bookbank point correctly again.

First thing is use partedUtil to identify what that 1 GB partition is. More instructions are here: https://kb.vmware.com/s/article/1036609

[root@xxxxxxx:~] partedUtil getptbl "/vmfs/devices/disks/mpx.vmhba32:C0:T0:L1

"

msdos

130 255 63 2097152

So there are no partitions on that LUN.

In effect I need to have that device deleted.

Turned out to be a HPE Embedded User Partition. Disable it as a Boot source and delete it in the server BIOS. That solves the problem.
