How to disable MSDP Catalog Resilience in Cloud Scale

Description

The MSDP catalog resilience feature can be disabled in Cloud Scale with the following steps:

1. Add the configuration item DisableSpadHA=true in the section [Cluster] of /msdp/data/dp1/pdvol/etc/puredisk/spa.cfg in each MSDP engine:
   1. Open an SSH session to the server which can access the Kubernetes cluster and use the kubectl command.
   2. Enter the bash of each MSDP engine using the following command:
      • kubectl exec -it -n <sample-cr-namespace> <sample-engine-pod> -c uss-engine -- bash
   3. Run the following command to update the configuration file:
      • sudo -u msdpsvc /usr/openv/pdde/pdag/bin/pdcfg --write=/msdp/data/dp1/pdvol/etc/puredisk/spa.cfg --section=Cluster --option=DisableSpadHA --value=true
2. Restart the MSDP services in the MSDP engines:
   1. Option 1: Manually delete all the MSDP engine pods:
      • kubectl delete <sample-engine-pod> -n <sample-cr-namespace>
   2. Option 2: Stop MSDP services in each MSDP engine pod. The MSDP service starts automatically.
      • kubectl exec <sample-engine-pod> -n <sample-cr-namespace> -c uss-engine -- /usr/openv/pdde/pdconfigure/pdde stop
