3.2.2 Downgrade support for EVA4400 and EVA6400/8400 controller software versions

This table shows downgrade support for the EVA4400 and EVA6400/8400 controller software versions. A bullet (•) indicates you can downgrade from the
version in the FROM column to the version in the TO column. A blank cell indicates a downgrade is not supported.
NOTES:
– If the EVA4400 controller contains cache DIMMs with either standard part number 2660-0281 or spare part number 587246-001 (or the controller has a label
with Min FW 09522000 affixed to it), you cannot downgrade from XCS 09522000.
– HP recommends only downgrading to XCS 09534000.
– Downgrading to a controller software version not listed in Table 3.2.2 may require an array initialization. Contact HP for recommendations and procedures for
downgrading.
