Red Hat
The remote CD-ROM is shown in the file /etc/fstab in Red Hat Linux, too. Check
the file before and after clicking the Mount Drive button. The new device you will
find is the remote CD-ROM. The following is an example of /etc/fstab.
Figure 4-22 Red Hat Linux - File /etc/fstab and the remote drive
The blade server became the owner of the media tray after clicking the Mount
Drive button. This is the reason why the remote CD-ROM is the device
/dev/cdrom and not /dev/cdrom1.
Mount the drive in your operating system:
mount /mnt/cdrom
To unmount, follow the steps beginning with step 6 on page 107.
4.4.5 Remote file
With the remote file feature you can use diskette and CD-ROM images as a drive
to mount.
When you download ISO images from the Internet, you do not have to create a
CD-ROM—you can use them directly as remote media.
To mount a file do the following:
1. Select Select File.
2. Click >>.
LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda3 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/cdrom1 /mnt/cdrom1 udf,iso9660 noauto,owner,kudzu,ro 0 0
/dev/sda /mnt/floppy auto noauto,owner,kudzu 0 0
Tip: You can create ISO images using tools such as IsoBuster
(http://www.smart-projects.net/isobuster/) and Magic ISO maker
(http://www.magiciso.com/). If you have a set of files that does not extend
1.44 MB, you alternatively can create a diskette disk image with one of these
tools.

3. Choose the disk image file you want to use and click Open.
4. For diskette images (that is, not ISO files), you are prompted as shown in
Figure 4-24.

Chapter 4. BladeCenter management module 117
If you click Yes, the file is uploaded to the RAM of the BladeCenter
management module. To upload the image it must not be bigger than 1.44
MB. This may take some time depending on the network connection. A
progress bar will appear.
If you click No, you additionally have to click Mount Drive to mount the drive
to the remote server. The file is not uploaded and is accessed remotely from
your local PC via the network. Subsequent file access from this remote file
will be at network speed. It is automatically unmounted when you close the
remote console window.
5. If you have an ISO image, click the Mount Drive button.
Windows-specific steps
The image file is now available as a drive in the Windows operating system.
Check in Windows Explorer for the new drive.
To unmount, launch the remote media Web interface, and complete the steps
beginning with step 6 on page 107.
Linux-specific steps
The remote file features work similar to the remote diskette feature, except that
you can use ISO image files too.
SUSE LINUX
Check the /etc/fstab file before and after you click the Mount Drive button to see
which is the new device. In Figure 4-25 on page 118 the ISO image is device
/dev/sr1.
Tip: The image will remain in the RAM and is accessible for the blade
server, which is the KVM owner until you unmount it using the Unmount
button. The management module is restarted or the firmware is updated.
When you change the KVM owner, the new owner can use the remote disk
image, too.

To unmount, follow the steps beginning with step 6 on page 107.
Red Hat
When using Red Hat Linux, the remote file is not mentioned in the file /etc/fstab.
As a result, you will have to try sda, sdb, sdc, etc. until you successfully connect
to the remote device.
In Figure 4-26 on page 119 the second try to mount the ISO image file was
successful.
