Thanks Andrew. To be clear, can I simply remove the host from each SAN without actually unmapping all the datastores / LUNS? <br />
<br />
I was worried about doing that since there is no server there to connect to and didn't want the SANs to freak out when it couldn't connect to the host to remove it. I may just leave it alone until I have time to be at the datacenter in case there is an issue. <br />
<br />
Thanks again as usual.

An ESXi 5.1 host was physically removed before iSCSI SAN storage was unmounted/detached/unmappe<wbr />d and the host rescanned. The host was / is being decommissioned and no VMs were running on it. It was removed from vCenter management a while back and was not part of a cluster. It had been powered off for about a month before being taken from the rack. <br />
<br />
I still see the host on the EMC and the HP SANs. Can I remove the host from the SANs without causing the SANs or other hosts to freeze up (all paths down or some other issue)? Is it better to just leave the removed host on the SANs? There are only 2 hosts here managed by vCenter and in a cluster so it's not a big cluster with several hosts. <br />
<br />
Thanks for any help

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.
