My first dW blog entry.
Some of my favoritre AIX update and migration tools (nimadm and multibos) have been enhanced to perform cool new tricks! In particular, multibos now supports AIX migrations not just updates to newer TLs and SPs. Unfortunately, from what I've read, you need to be running AIX 6.1 first. So I won't be able to use multibos to migrate from AIX 5.3 to 6.1. So I'll use nimadm instead. Some brief details are provided below. Refer to the online AIX documentation for more information.
Enhanced nimadm command.
The nimadm command is enhanced to allow the system administrator to do the following:
- Use a NIM client’s rootvg to create a NIM mksysb resource that has been migrated to a new version or release level of AIX.
- Use a NIM mksysb resource to create a NIM mksysb resource that is migrated to a new version or release level of AIX.
- Use a NIM mksysb resource to restore to a free disk, or disks, on a NIM client and simultaneously migrate to a new version or release level of AIX.
- To create a migrated new mksysb resource of a client with the filename nim1, type the following:
Enhanced multibos command.
# nimadm -c aix1 -s spot1 -l lpp1 -O /exp
- To create a new migrated mksysb resource with the filename nim3 from an existing NIM mksysb resource, type the following:
# nimadm -s spot1 -l lpp1 -j vg00 -Y -T nim2 -O /export/mksysb/m2 -N nim3
- To use an existing mksysb file /backups/mksysb1 to populate the standby instance of rootvg, enter the following command:
# multibos -M /backups/mksysb1 -sX
-M file Specifies a file that contains an mksysb image. The mksysb image must have been created using the mksysb -M command beginning with AIX 6.1 with 6100-02.
