This is on HPUX 11.11, RP5470 server.
Very basic question here. In order to do some load balancing, I am doing the vgreduce and vgextend on a volume group. This is on a volume group that runs oracle financials. Question: does the database and all application processing have to be stopped in order to do this? Or, can vgreduce and vgextend be issued when the application and database is running?
Solved! Go to Solution.

Yes, you are quite safe performing the swap of the primary and secondary pvlinks.

Re: vgreduce and vgextend question
its always recommended to take backup both OS and database when you reduce or extend the the file system. otherwise if somethin goes wrong you may not get back your valuable data.
>>does the database and all application processing have to be stopped in order to do this?
yeah certainly
>>can vgreduce and vgextend be issued when the application and database is running?
vgextend doesn't need any downtime. but vgreduce is very very sensitive.
you may did this using OnlineJFS. it'll not need any downtime if you have proper backup.
