Docker daemon start‑up delay causing command blockage The upgrade process hangs while executing /usr/bin/docker network inspect powerprotect_backend . This occurs because the Docker daemon is still in a starting state, which can happen due to system slowness or network‑related delays. When the daemon has not fully initialized, the docker network inspect command blocks indefinitely, preventing the upgrade script from completing.
The permanent fix is in PPDM 19.22 Patch 1 and later. If you cannot wait for 19.22 patch 1, contact Dell support to get the updated update.sh script. The new update.sh script is modified to wait for the docker daemon. Replace it with the original script /data01/brs/upgrade/update.sh and rerun the upgrade.
