Can't mount /dev/cdrom on ESX35

[ap88400]

Hello everybody,

since ESX 3.5 64607 to ESX 3.5 SP2 I cannot mount anymore CDs or DVDs in COS.

Hardware is some Fujitsu-Siemens FSC RX300-S4, with latest firmware.

mount /dev/cdrom /mnt/cdrom/

mount: /dev/cdrom is not a valid block device

In /boot/grub/grub.conf there is nothing belonging to the IDE CD-R/DVD

I also cannot connect the drive to a vm.

The problem exists at the time on several ESX Hosts, I think it has to deal with the CD-R/DVD Problem

Thank you, Armin

This will also depend on how your cd/dvd drive was recognized when the server booted. Usually, the cd will be automatically detected, and will be linked to /dev/cdrom, but this isn't always the case. You should be able to run 'dmesg|grep -i cd', and look through that output to see how your cd was detected, and to what device it was mapped to.

Typically, an ide cd drive will be something like /dev/hdc, and scsi will be /dev/sdc, but I've also seen /dev/sg0. The dmesg output should tell you.

Ok, I've got the answer from FSC Support .

We have to change the FSC RX300 BIOS Settings:

Advanced --> Peripheral Configuration --> ATA Controller Config

--> S-ATA Mode
