AFAICT, there's not enough space to move the data within the current hdd pool; we'll need to ask DSI to install the first two disks before shuffling the data around.

We'll want to replace one of the 8TB pairs. They're pretty much balanced and have the same purchase date, so which one doesn't matter much.

Overview of the system :

2 slots availables (10 slot occupied on a total of 12)
system installed on 2 disks ssd disk (wwn-0x500a075122f366e4 and wwn-0x500a075122f357f1)
2 zfs pools

So according to this, and you have suggested, the plan can be:

add 2 new disks on the last 2 slots available
Declare the new mirror:

zpool add hdd mirror <disk1> <disk2>

remove mirror-2 from the zfs pool

zpool remove hdd mirror-2

wait for the end of the removal
Ask for the replacement of disks in slot 4 (5000c500ae759873 / Serial ZA1G3R1S ) and 6 (5000c500ae750b2f / Serial ZA1G3H81) by the last 2 new disks
Add the 2 new disks in the zfs pool :

zpool add hdd mirror <dnew isk1> <new disk2>

Mail sent to the dsi to request the installation of 2 of the new disks

2 disks were installed on the 2 remaining free slots.
They are detected by the raid card but need to be configured in JBOD mode.
It's postponed to Thursday morning as granet is sensible until a demonstration on wednesday afternoon.

The disk to remove will be:

root@granet:~# ls -l /dev/disk/by-id/ | grep -e 'scsi-35000c500ae750b2f ' -e 'scsi-35000c500ae759873 '

lrwxrwxrwx 1 root root  9 Dec 14 20:57 scsi-35000c500ae759873 -> ../../sdd

To identify the disks to replace, the front led can be activated via the idrac interface.
The disks are :
scsi-35000c500ae759873 | /dev/sdd: Serial ZA1G3R1S -> Physical Disk 0:1:3
scsi-35000c500ae750b2f | /dev/sdf : Serial ZA1G3H81 -> Physical Disk 0:1:5

The 2 remaining disks were inserted in place of the 2 old sdd and sdf.
They needed to be configured in JBOD mode:

root@granet:~# megacli -PDMakeJBOD  -physdrv[32:3] -a0
                                     
Adapter: 0: EnclId-32 SlotId-3 state changed to JBOD.

Exit Code: 0x00
root@granet:~# megacli -PDMakeJBOD  -physdrv[32:5] -a0
                                     
Adapter: 0: EnclId-32 SlotId-5 state changed to JBOD.

Exit Code: 0x00

After that they were correctly detected by the system:
