device_remap
device_remap(1M) System Administration Commands device_remap(1M) 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
