In my home lab one of my esxi hosts had 3 datastores
ESXi2-datastore1
ESXi2-datastore2
ESXi2-datastore3
I deleted ESXi2-datastore2, but so some reason ESXi2-datastore3 disappeared too.

From what I can see for the missing data store the SAS drive still holds an entry vmfs and furthermore I can access the contents from the esxi shell
partedUtil getptbl /vmfs/devices/disks/naa.600508b1001030393231374430300500

in theory I can copy the stuff over, and wipe this drive but I am curious if there is an elegant way to fix this!?

both datastores were not on the same disk or LUN ?

can you execute

esxcfg-volume -l

at the console, do you get any results ?

no 3 local sas drives and each datastore was on a separate drive

/vmfs/volumes/54982575-7dfde3e1-9cc0-1cc1de6f132c # esxcfg-volume -l
/vmfs/volumes/54982575-7dfde3e1-9cc0-1cc1de6f132c #

if you click Add Storage does it detect it as an existing LUN/datastore, or want to overwrite it ?

It would appear to have lost the meta data some how. and/or symbolic link.

Also a re-scan of the storage system ?

re-scanning did not help or refresh.

if I try to add storage - it would appear it wants to overwrite it so I cancelled
