We can remove it actually? and can be rediscovered? So this action is just delete the device file, not the data?
In the first, the newly added disk is recognized as a hdisk1. Then I format it with
then it becomes the array candidate pdisk5. Then I use.
The disk can be added, but the get the warning such as: the disk is not used for parity and not restriped". I have not captured the exact output.
--> this means that the new disk is only used for data and not used for parity checks and stripped data like Raid 5 behavior?
I though I should try with this first instead of "Add disks to an existing ..." . As after adding, the re-contruct option is not effective.
Here is the menu-list command:
I followed this for what I have done IBM Knowledge Center Error
And this for rebuild -->PCI-X SCSI RAID Controller Reference Guide for AIX. Actually not having the chance to use it as mentioned above. IBM Knowledge Center Error
You have any idea for this?
So just wonder, as recommended by you, we should unmount all devices/filesystems, but do this mean downtime also in application and not really the "hot-swap". In what case we can do an online replacement? As read, the disk is hot-swap, it can be done online, right? Please advise.

If you look at the pdisks in the raid5 pdisk5
We can see it has 6 pdisks: 6x142.8=856.8 GB
But with Raid5, we have total size=total disk -1 means 5x142.8=714GB. It matched with 714.3 GB above.
So the OS should recognize the hdisk5 and its VG is 714GB instead of only 540GB
