For an AIX 5L NIM server recovery, the same command is used: # installios -? Usage: installios [-h hmc -s managed_sys -p partition -r profile ] -S netmask -i client_addr -g gateway -d source_dir [-P speed] [-D duplex] [-n] [-N] [-l language] [-L location] | -u[f|U] This command can be run either on the command line or using the smitty installios command. For this command to work, SSH needs to be configured between the NIM server and the HMC. Example 5-9 shows the output of the smitty installios command that accepts the same information as the installios command. Note: If you prefer to use NIM in the same way as for other servers, you can generate the Virtual I/O Server backup using the -mksysb flag. See 5.2.4, “Backing up on a file system” on page 282, Backup to NIM for steps to create the required NIM resources. Example 5-9 AIX 5L smitty installios menu Type or select values in entry fields. Press Enter AFTER making all desired changes. [TOP] [Entry Fields] * Select or specify software source [cd0] + to initialize environment HMC Name [] Managed System Name [] Partition Name [] Partition Profile Name [] Primary Network Install Interface * IP Address Used by Machine [] * Subnetmask Used by Machine [] * Default Gateway Used by Machine [] Network Speed Setting [100] + Network Duplex Setting [full] + Language to Install [en_US] + Configure Client Network After Installation [yes] + ACCEPT I/O Server License Agreement? [no] + [BOTTOM] The AIX 5L installios command uses SSH commands to the HMC to shut down the LPAR and reboot it to get both the MAC address and to start the NIM 288 <strong>Advanced</strong> <strong>POWER</strong> <strong>Virtualization</strong> on IBM System p5
installation. Either a DVD backup or a file backup can be used to perform this restore. You are now ready to do a NIM install of the Virtual I/O Server. 5.3 Rebuilding the Virtual I/O Server This section describes what to do if there are no valid backup devices or backup images. In this case, you must install a new Virtual I/O Server. In the following discussion, we assume that the partition definitions of the Virtual I/O Server and of all clients on the HMC are still available. We describe how we rebuilt our configuration of network and SCSI configurations. It is useful to generate a System Plan on the HMC as documentation of partition profiles, settings, slot numbers, and so on. Example 5-10 shows the command to create a System Plan for a managed system. Note that the file name must have the extension .sysplan.
