Well our stack is a strange breed then, 3xHPE and 3xH3C..
The command "display device manuinfo" returns the following:, with some irrelevant data edited our:
Slot 1:
DEVICE_NAME : A5800-24G JC100A
DEVICE_SERIAL_NUMBER : CN2BBFN0F9
VENDOR_NAME : HP
Slot 2:
DEVICE_NAME : S5820X-28S
DEVICE_SERIAL_NUMBER : 210235A370H10C000035
VENDOR_NAME : H3C
Slot 3:
DEVICE_NAME : A5800-24G-SFP JC103A
DEVICE_SERIAL_NUMBER : CN18BFR06X
VENDOR_NAME : HP
Slot 4:
DEVICE_NAME : A5800-24G JC100A
DEVICE_SERIAL_NUMBER : CN18BFN034
VENDOR_NAME : HP
Slot 5:
DEVICE_NAME : S5820X-28S
DEVICE_SERIAL_NUMBER : 210235A370H117000005
VENDOR_NAME : H3C
Slot 6:
DEVICE_NAME : S5800-32F
DEVICE_SERIAL_NUMBER : 210235A374H115000027
VENDOR_NAME : H3C
And as this its been working fine for 3+ years with 5.20 1808P21, with "slot 1" acting as the commander. But when we applied 1810P12 today the H3C ones said "invalid version" and we had to revert back to the old firmware.
