The VAMI is unable to detect the ISO file after it has been attached via the CD/DVD option on the vLR vLSR VM.
The ISO is not detected via the CLI.
It is also not visible in the VAMI under:
Updates → Available Updates → Check Updates → Check CD-ROM.
VMware Live Site Recovery 8.x, 9.0.2.x
VMware Live Recovery 8.x, 9.0.2.x
The ISO may be connected, but because the emulated CD tray may be stuck "open", the OS has not yet been allowed to mount the CD-ROM.
Refresh the VAMI site on your browser to see if the CD-ROM is not seen in the updates area.
