I was looking at this:
https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2004582

Is there a way to specify the LUN ID to install to? Was hoping for creating a general script that installs to a specified lun on several different hosts.

normally, you would select a LUN, which is 0 (bootable LUN).

and then later connect all you other LUNs, otherwise there is a danger you overwite an existing LUN.

Yes, there is no full proof way of selecting the intended lun in a mix of luns in the script?

no, it would just select the next storage adaptor.

hence why, you normally only present LUN0 at install time, and then later present the additional LUNs or datastores.

It also requires hard configuration of the BIOS in the FC or iSCSI HBA to be enabled, at a hardware level, so the HBA can BOOT from LUN, before you run the script and installer.

a bit like setting PXE in the BIOS for a PC to BOOT from LAN!
