1 - Do not just shove the units in! You must use "concurrent
maintenance".
Use iNav! Especially for those who don't do this often.
Configuration and Service, Hardware, Disk Units,
Right click "By Location" and select Graphical View. Pick an empty slot.
Empty slots are white, full slots are blue. Right click on that empty
slot and select "Install Disk Unit". Pay close attention to the step in
the wizard that says "Support the bottom of the new disk unit as you slide
it >>>>>HALF WAY<<<<< into the slot. Do NOT push it in any further. Then
click Enable Slot."
After you get all your disks installed this way, continue. The above step
will not have any performance impact on your system.
I'll assume you are using RAID. Continue on AFTER you've installed all
disk drives following steps above.
STRSST
3. Work with disk units
2. Work with disk configuration
8. Work with device parity protection
2. Include unit in device parity protection
-or, if you've added several units, then one of the following:
3. Start device parity protection - RAID 5
4. Start device parity protection - RAID 6
5. Start device parity protection - RAID 5 with hot spare
6. Start device parity protection - RAID 6 with hot spare
This will take a long time and I don't "think" this has much of a
performance impact.
Once that is done then take:
STRSST
3. Work with disk units
2. Work with disk configuration
4. Add units to ASPs and balance data
This MAY have a performance impact.
You can check the progress in STRSST or I think you can check it outside
of STRSST with CHKASPBAL.
You can bypass iNav by doing this:

STRSST
1. Start a service tool
7. Hardware service manager
1. Packaging hardware resources (systems, frames, cards,...)
Use "9=Hardware contained within package" on the frame you are adding the
disk drives to.
F7=Include empty positions and not owned positions
Pick one that says "Empty Position".
Use "2=Toggle identify indicator state" to see if you can turn the light
on by that slot to verify you have the right one. Use the toggle again to
turn the light off.
Notice "Unit ID" in the top right and position in the subfile? Write
those down. Return back to "Hardware Service Manager". Select "8. Device
Concurrent Maintenance". Enter the data from the above. Sample might be
U5787.001.1234567-P3-D4.
Insert the disk HALF WAY in.
3=Concurrent maintenance
8. Device Concurrent Maintenance
Figuring out that "Physical Location" can be tricky.
