In turn, if I now run "bootlist -m normal -o" I get..
Why is it showing there? I am concerned if a reboot happens I may not be able to boot.. how can I remove it and assign hdisk20 which is the replacement for hdisk14 in rootvg... or do I need to do anything further at this point?
There are two commands you need to know: "bosboot" and "bootlist".
With "bootlist" you can set (or display) the order (in NVRAM) in which devices are used to boot from. There are basically 2 lists of such boot devices, "normal" and "service". There is a "key position" that determines which boot list is getting used. Back then, in the times of physical machines, this was really a lock with a key and the key could be in one of 3 possible positions, "normal", "service" (sometimes named "maint") and "lock". Today this is only a virtual construct, but the terminology stuck.
With "bosboot" you bring a boot image to boot from onto a device. This copies the code that is executed during the boot onto the device you designated as boot device with "bootlist".
I suggest you read carefully the man pages of both commands, then read them again. You can render the system unusable with these commands, so spend some time and effort to really, firmly understand what they are doing. Only then use them to alter the boot list. (You will need both of them - proceed only if you understand why.)

This may sound like an absolute rookie question, and it is.

Now we've suddenly got a new IBM server and I don't even know how to check if it is connected to the switch.
Can someone... (1 Reply)

We are in the process of adding two new disks to the disk arrays so as to make them available to the existing... (3 Replies)
