Cisco Nexus 9K Boot Loop After Upgrade: Error Loading Shared Libraries

m3tr0x

Hello Cisco Community,


I'm facing a critical issue with my Cisco Nexus Nexus9000 93180YC-EX switch after upgrading its software & BIOS using the following image - nxos64-cs.10.2.4.M.bin
The switch entered a boot loop with the following error message:

"Starting hybrid sysmgr ...
/isan/sbin/sysmgr: error while loading shared libraries: libcrdcfgdata.so: cannot open shared object file: No such file or directory
INIT: Id "lcsm" respawning too fast: disabled for 5 minutes"

I have tried the following troubleshooting steps:
Rebooted the switch multiple times, but it keeps getting stuck in the same boot loop.
The upgrade went well and all verifications passed successfully.

I do have access to bash4.4 shell if needed.

I would appreciate any assistance in resolving this issue. Has anyone else faced a similar issue after upgrading their Nexus 9K switch? How did you resolve it?

Thank you in advance for your help.

●    The 64-bit Cisco NX-OS image filename that begins with "nxos64-cs” (for example, nxos64-cs.10.2.4.M.bin). This image is supported on all Cisco Nexus 9000 series fixed switches as well as 9000 Modular switches with FM-E/FM-E2/FM-G.

●    The 64-bit Cisco NX-OS image filename that begins with "nxos64-msll” (for example, nxos64-msll.10.2.4.M.bin). This image is supported on Cisco Nexus 9000 -R and -R2 series modular switches.

Thanks. So according to you, I've used the correct Image. So what can be the root cause to my issue and how I ca resolve it?
