Hi community
yesterday I tried to upgrade my ACI fabric with a current version 2.1(1h) to the recommended version 4.2(7f), so to achieve the upgrade I need to pass by an intermediate version which is the 2.2(2d).
the upgrade from version 2.1(1h) => 2.2(2d) is worked properly and all the fabric is fine. but when I tried to complete the upgrade to my target version 4.2(7f), I have faced an issue with switches of the fabric, I find that only one leaf is upgraded properly to version 14.2.7f but the other switches (LEAF2, SPINE1-2) are failed the upgrade and they stuck in the loader mode, even I tried to boot the switches manually using the CLI on the correct version with no way.
this some hardware pieces of information related to my fabric :
Two Nexus 9336PQ Switches Spines, Two Nexus 9396PX Switches Leafs,Two 2232TM-E Fabric Extenders
and this the upgrade path to the target version:
ACI version Path Upgrade duration
1 2.1(1h) → 2.2(4p)
2 2.2(4p) → 4.2(7f)
Target version of Switches:
| Target version | supported spine hardware | supported leaf hardware | Actual
device
support |
| 12.2(4) | N9K-C9336PQ | N9K-C9396PX | yes |
| 14.2(7) | N9K-C9336PQ | N9K-C9396PX | yes |
below you will find attached an output terminal of the upgrade of one switch to version 14.2(7).
is there any solution to fix this issue?
thanks.
