Installing a physical processor after ESX 3.5 initial install

[strich55]

Hi,

quick and simple question : if I install ESX 3.5 on a host with a single processor, will I be able to add a second physical processor on that host without having to re-install ESX?

second quick and simple question : if I install ESX 3.5 on a host and later on, I install a scsi card for a tape, will that scsi card be automatically detected when the machine is restarted?

Thank you

Both questions can be answered with Yes.

as long as your scsi card is on the HCL of VMware there should be no problems.

Be careful if installing PCI cards after the initial installation. If your device numbers change based on PCI bus scan order, you may lose the ability to talk to one or more of your existing devices. For example, if you install your new SCSI controller in a PCI slot that gets scanned before your existing SCSI controller (vmhba0, for example) then the new controller will become vmhba0 and your original one will become vmhba1. So...can you add an additional controller at a later date? Absolutely. Just be careful when you do.
