Is the error message "cp: command not found"? Or "/.cdrom/: device not found"? Or "psychic help forums: you already know what the problem is"? Or what?

Different architectures have different start-up script arrangements. Ubuntu for example replaces the original /tmp/ with a virtual file system at some point during the boot process so it could be that your copy succeeds but the directory is shadowed later on in the boot process. What are you using for the CD image?

Can all files under /tmp be safely removed

I wanted to know whether all files under /tmp can be safely removed.

NAME
device_remap - administer the Solaris I/O remapping feature SYNOPSIS
/usr/platform/sun4v/sbin/device_remap [-v | -R dir] DESCRIPTION
Certain multi-node sun4v platforms, such as T5440 and T5240 servers, have an integrated PCI topology that cause the I/O device paths to change in a CPU node failover condition. The device remapping script, device_remap, remaps the device paths in /etc/path_to_inst file and the symlinks under /dev to match the hardware. OPTIONS
The following options are supported: -v Displays the /etc/path_to_inst and /dev symlink changes. -R dir Perform remapping on the /etc/path_to_inst and /etc/path_to_inst files in the root image at dir. USAGE
The primary function of device_remap is to remap the device paths in the /etc/path_to_inst file and the symlinks under /dev in a CPU node failover condition to match the hardware. After adding CPU node(s) or removing CPU node(s), boot the system to the OBP prompt and use the following procedure: 1. Boot either the failsafe miniroot using: boot -F failsafe , or an install miniroot using boot net -s or similar command. 2. Mount the root disk as /mnt. 3. Change directory to the mounted root disk: # cd /mnt 4. Run device_remap script: # /mnt/usr/platform/sun4v/sbin/device_remap 5. Boot the system from disk. All the error messages are self-explanatory, except for the error message "missing ioaliases node" which means the firmware on the system does not support device remapping. EXAMPLES
Example 1 Displaying Changes Following Failover The following command displays the path_to_inst and /dev changes following a CPU node failover. # device_remap -v Example 2 Changing Directory Prior to Any Changes The following command changes the directory on which the boot image is mounted prior to making any changes. # device_remap -R /newroot ATTRIBUTES
