After the upgrade to AOS 5.1.5, my LCM console gave the following message. Json Rpc request for unkown Rpc object LifeCycleManager Error message You can solve this issue by doing the following steps: 1). Verified that the PRISM shows: JSON RPC request error. 2). verified from ~$ zkls /appliance/logical/pyleaders/lcm_leader/   one of the CVM was not listed. I have 9. n_0000000096 n_0000000097 n_0000000098 n_0000000099 n_0000000100 n_0000000101 n_0000000102 n_0000000103 3). Verified One of the CVM .101 has .genesis_restart_required_path file. ~$  allssh "ls -latr ~/.genesis_restart_required_path" 4). Removed the file and restarted genesis on all the CVMs. ~$  rm .genesis_restart_required_path ~$  allssh genesis restart 5). Verified the issue does not exist anymore.

Life Cycle Management has designed to take care of all the necessary Dell tools, like the ones I mentioned in an earlier post: https://softwaredriven.blogspot.nl/2017/10/life-cycle-management-12-voor-dell-xc.html You can update components on production clusters in use. But it is recommended for the first time of running LCM 1.2, to do it during off-hours as the cluster requires a reboot per node to install iSM and PT Agent . This two components are necessary before the LCM can download the payload. Once the payload is downloaded, you can run an inventory again so LCM can determine what components need to be updated. Depending on the size of the cluster, this can take up to 10 minutes (for 3 node cluster) or longer depending on the number of components to be found. When you update a component, LCM put the host in maintenance mode. Then LCM put all the components in a queue to be updated. At the end of the update process, the system will do a reboot. After the reboot, the...

Life Cycle Manager allows you to view all software and firmware updates from a single pane of glass. From the LCM dashboard you can do an inventory for all the entities in the cluster. LCM support new features for the Dell XC platforms in version 1.2. LCM is supported for the Dell 13G hardware family on AHV and on ESXi 5.5 and 6.0. This release adds LCM inventory and update support for the following components: • BIOS • iDRAC • HBA controller • NIC • Data drives (SSD and HDD) All the Dell XC  updates are packaged within a Payload . A payload level determines what firmware versions are supported for LCM update. You can see on a fresh updated LCM on a Dell XC cluster the following dashboard: The Prism UI does not provide visiblility into the payload. Check this PDF for the current payloads for LCM 1.2. https://s3.amazonaws.com/ntnx-portal/documentation/kb/lcm-dell-payloads-v1.2.pdf You can see multiple software the LCM has inventoried. I explain some of th...
