1. Configuration inconsistency
2. Type 2 (QoSMgr Qos configuration incompatible)

Action Taken :

1)  Internal storage got corrupted.

1) Event:E_DEBUG, length:71, at 756769 usecs after Fri Jun 29 19:19:02 2018

    [18] nve_mgr_mcecm_type1_glbl_cfg_compat_check: unable to get local tlv
---
2) Compared the configuration on N3K 01 and 02 and all are same.
3) Reloaded both N3Ks one by one, then fixed the TLV inconsistency
4) Reloaded the N3K-01 by ascii option, then cleared the QosMgr inconsistency
