Hi, I have a standard HP server with Esxi 5.1 with multiple VMs. I have 2 usb disks (they are the same). 1 is mapped on my virtual sbs, the second is mapped on my vcenter server. One day I saw that the usb on vcenter was not showing and from that day we are unable to see it. We have tried to;
Reboot the vcenter server
Reboot the Esxi server
Changed the power wire on the usb drive
Change the usb port used
Tried the disk on a workstation; working fine
I have no problem with the other disk mapped on the sbs. If I go in the properties of the vcenter server, I don't see the usb drive in my peripherals. If I try to delete the usb adaptor, I have an error saying (translated from french); cannot finish operation because of a concurrent modification by another operation
If I try to add the usb drive, I have the option to add it so the server sees it. I choose my drive, click on next. When done, still in the properties of the VM in the hardware tab, it shows as disconnected. After that in the vsphere client running on vcenter server, I have the same message as stated above which is;
cannot finish operation because of a concurrent modification by another operation
If I return in the hardware tab of my vcenter vm, the usb disk is not there.
Any ideas what I could do?
Thanks
