Hello Team,
When upgrading Cisco ACI fabric from 2.1(1h) to 4.2(7f): the upgrade to 2.2(4p) went OK, but the upgrade from 2.2(4p) to 4.2(7f) has failed, the switch goes into the loader mode and even when we force it to boot on a specific target image from bootflash, it shows us this errors and hangs:
May 22 17:42:20 %SYSMGR-3-UNACCEPTABLE_WAIT Service "nginx", no response from System Manager after 30 seconds. Terminating.
May 22 17:42:25 %SYSMGR-3-CORE_OP_FAILED Core operation failed: core_server_main: unable to send message on vdc 2: Inappropriate ioctl for device (25).
May 22 17:45:18 %SYSMGR-3-CORE_OP_FAILED Core operation failed: send_msg_to_ccdmon: mts_send failed, ret_val: -1, error: No route to host(113)
May 22 17:45:18 %SYSMGR-3-CORE_OP_FAILED Core operation failed: perform_upload: upload start failed
What could be the problem ( we check all compatibility matrix and even no EPLD available to download for this switch model: Nexus 9336PQ Switches)?
Thanks.
