Difference between Major and Minor in AIX

Major and Minor what?
Hi
what is the use of the major and minor number in AIX
A quick search on "major and minor number" in google produces lots of result
major and minor number in unix - Google Search
or tip of info from my side
If you run ASM, the major/minor numbers of your disk devices compared with the ASM devices are the only way for you to find out if a disk is in use or not.
In addition they help you to find out which logdevice is too small for example - the errpt only gives you the major/minor numbers but doesnt tell you the name of the logfile.
If you run a veritas cluster, you have to tell the clusterconfig which major number your volumegroups have to enable the cluster to vary it on ...
ODM manages filesystems and rawdevices via major/minor and determines which logdevice corresponds to which filesystem
Kind regards

In HACMP it is wise to use the same major number for each volume group throughout the cluster - makes identifikation of corresponding disks so much easier.
I hope this helps.
