Solution Type Technical Instruction Sure Solution 1009400.1 : Loopback file driver (lofi) & CDROM : How to access CDROM images via lofi.
PreviouslyPublishedAs 212997 Description To allow access to CDROM images without the additional CDROM library hardware and to also allow burning of the images on a as needed basis. Overview OR gerenal outline of the procedure is listed below:- - Setup Hardware. - Install Solaris[TM] OS ( Solaris[TM] 8 2/02 and above. REMINDER: Solaris[TM] 8 is EOL ) - Install Recommended patches for Solaris OS - Install CD Read/Write software from Solaris supplement CDROM - Create CDROM images. - Create device file to link the CDROM images. - Edit the dfstab file to share the images. - Create a Startup file to maintain device file link(s). - reboot. - Create a MOTD file that points users to instructions for burning and using images. Steps to Follow Procedure to access & burn CDROM images via lofi : (1) Setup Hardware. Example of system setup - Hardware Configuration: ? Sun Ultra 60 ? 1 - 9.0G drive (Internal c0t0d0) ? 1 - 4.2G drive (Internal c0t1d0) ? 1 - Onboard CDROM drive (Internal) ? 1 - Yamaha CDROM burner (External) ? 1 - 4mm dat tape drive (External) (2) Install Solaris OS ( Solaris[TM] 8 2/02 and above ) Be sure to keep in mind the amount of space needed for CDROM images. (3) Install the recommended patch cluster located on sunsolve. (4) Install CD Read/Write software from Solaris supplement CDROM e.g. "CD Read/Write 1.0" software from Solaris 8 2/02 supplement CDROM. (5) Create CDROM images (5-1) Create image source directory and image mount points. Example: # mkdir /image_source # mkdir /images/gen_tk # mkdir /images/clust_tk # mkdir /images/VTS-v3 (5-2) Create images. Mount appropriate CD in CDROM drive, create image using mkisofs command. Example: # mkisofs -r -v -o /image_source/gen_tk.img /cdrom/gen_tk # mkisofs -r -v -o /image_source/clust_tk.img /cdrom/clust_tk # mkisofs -r -v -o /image_source/VTS-v3.img /cdrom/cdrom (6) Create device file to link the CDROM images Example: # lofiadm -a /image_source/gen_tk.img /dev/lofi/1 # lofiadm -a /image_source/clust_tk.img /dev/lofi/2 # lofiadm -a /image_source/VTS-v3.img /dev/lofi/3 (7) Edit the dfstab file to share the images (7-1) Test mount the images: Example: # mount -F hsfs -o ro /dev/lofi/1 /images/gen_tk # mount -F hsfs -o ro /dev/lofi/2 /images/clust_tk # mount -F hsfs -o ro /dev/lofi/3 /images/VTS-v3 (7-2) Share out the image mounts by editing the /etc/dfstab file ::::::::::::: /etc/dfstab ::::::::::::: share -F nfs -o ro /images/gen_tk share -F nfs -o ro /images/clust_tk share -F nfs -o ro /images/VTS-v3 (8) Create a Startup file to maintain device file link(s) ? At this point the association of the device file and the image is temporary. If a reboot is done the images will not mount. lofi will forget the associations. To make this a static configuration create the following script/file. ::::::::::::::::::: /etc/rc2.d/S94lofi ::::::::::::::::::: #!/bin/sh # lofiadm -a /image_source/gen_tk.img /dev/lofi/1 lofiadm -a /image_source/clust_tk.img /dev/lofi/2 lofiadm -a /image_source/VTS-v3.img /dev/lofi/3 mount -F hsfs -o ro /dev/lofi/1 /images/gen_tk mount -F hsfs -o ro /dev/lofi/2 /images/clust_tk mount -F hsfs -o ro /dev/lofi/3 /images/VTS-v3 (9) Reboot Verify with df -k and share AFTER booting (10) Create a MOTD file that points users to instructions for burning and using images. Refer to Technical Instruction <Document: 1018811.1> for instructions for CDROM burning.
