Restoring from file system using the installios command
The restore of a Virtual I/O Server file system backup is done using the
installios command of the HMC or AIX 5L. For a restore, the tar file must be
located either on the HMC, an NFS-accessible directory, or a DVD. To make the
tar file created with the backupios command accessible for restore, we performed
the following steps:
1. Create a directory named backup using the mkdir /home/padmin/backup
command.
2. Check that the NFS server is exporting a file system with the showmount
nfs_server command.
3. Mount the NFS exported file system onto the backup directory.
4. Copy the tar file created in 5.2.4, “Backing up on a file system” on page 282 to
the NFS mounted directory using the following command:
$ cp /home/padmin/backup_loc/nim_resources.tar /home/padmin/backup
At this stage, the backup is ready to be restored to the Virtual I/O Server partition
using the installios command on the HMC or an AIX 5L partition that is a NIM
server. The restore procedure will shut down the Virtual I/O Server partition if it is
still running. The following is an example of the command help:
hscroot@server1:~> installios -?
installios: usage: installios [-s managed_sys -S netmask -p partition
-r profile -i client_addr -d source_dir -m mac_addr
-g gateway [-P speed] [-D duplex] [-n] [-l language]]
| -u
Using the installios command, the -s managed_sys option requires the HMC
defined system name, the -p partition option requires the name of the VIOS
partition, and the -r profile option requires the partition profile you want to use to
boot the VIOS partition during the recovery.
If you do not specify the -m flag and include the MAC address of the VIOS being
restored, the restore will take longer as the installios command shuts down the
VIOS and boots it in SMS to determine the MAC address. The following is an
example of the command usage:
hscroot@server1:~> installios -s p550-ITSO -S 255.255.255.0 -p
testvios2 -r default -i 9.3.5.125 -d 9.3.5.126:/export_fs -m
00:02:55:d3:dc:34 -g 9.3.5.41
Following this command, NIMOL on the HMC takes over the NIM process and
mounts the exported file system to process the backupios tar file created on the
VIOS previously. The HMC NIM then proceeds with a normal install of the VIOS
and one final reboot of the partition completes the install.
