You can restore the Virtual I/O Server base code,
applied fix packs, custom device drivers to support disk subsystems,
and some user-defined metadata from a mksysb image stored in a remote
file system.
Before you start, complete the following tasks:
- Ensure that the server to which you plan to restore the Virtual I/O Server is defined
as a Network Installation Management (NIM) resource.
- Ensure that the mksysb file (that contains the backup of the Virtual I/O Server) is on the
NIM server.
- If the system is managed by the Integrated Virtualization Manager, then you need to
restore your partition profile data for the management partition and
its clients before you restore the Virtual I/O Server. For instructions, see Backing up and restoring
partition data. (Alternatively, you can use the rstprofdata command.)
To restore the Virtual I/O Server from a mksysb
image in a file system, complete the following tasks:
- Define the mksysb file as a NIM resource, specifically,
a NIM object, by running the nim command. To view a detailed description of the nim command,
see nim Command. For example:
nim -o define -t mksysb -a server=servername -alocation=/export/ios_backup/
filename.mksysb objectname
Where:- servername is the name of the server
that holds the NIM resource.
- filename is the name of the mksysb file.
- objectname is the name by which NIM registers
and recognizes the mksysb file.
- Define a Shared Product Object Tree (SPOT) resource for
the mksysb file by running the nim command. For example:
nim -o define -t spot -a server=servername -a location=/export/ios_backup/
SPOT -a source=objectname SPOTname
Where:- servername is the name of the server
that holds the NIM resource.
- objectname is the name by which NIM registers
and recognizes the mksysb file.
- SPOTname is the NIM object name
for the mksysb image that was created in the previous step.
- Install the Virtual I/O Server from the mksysb
file using the smit command. For
example:
smit nim_bosinst
Ensure
the following entry fields contain the following specifications.Table 1. Specifications for the SMIT command| Field |
Specification |
|---|
| Installation TYPE |
mksysb |
| SPOT |
SPOTname from step 3 |
| MKSYSB |
objectname from step 2 |
| Remain NIM client after install? |
no |
- Start the Virtual I/O Server logical
partition. For instructions, see step 3, Boot the Virtual I/O Server, of Installing the Virtual I/O Server using NIM.
- If you restored the Virtual I/O Server to a different
system from which it was backed up, you must restore the user-defined
virtual devices. For instructions, see Restoring user-defined virtual devices.
