Symptoms

The following error message is received when trying to upgrade: # system upgrade 6.2.1.30-663869.rpm ** This command is deprecated and will be unavailable in future releases. Use 'system upgrade start' or 'system upgrade precheck' instead. The 'system upgrade' command upgrades the Data Domain OS. File access is interrupted during the upgrade. The system reboots automatically after the upgrade. Are you sure? (yes|no) [no]: yes ok, proceeding. **** Upgrade failed: another upgrade is in progress.

Cause

This error only occurs on DD HA configurations. Network routing and HA code can affect peer node communication, causing RPC errors at running command-line interface (CLI). In the logs, entries such below are seen: [messages.engineering] Oct 13 13:07:58 localhost reg_async[29701]: NOTICE: Run: chroot /ddr/aspirin-rootfs-CentOS/ /bin/bash -c 'while ip rule delete table tethMa 2>/dev/null; do :; done; exit 0;' 2>&1 Oct 13 13:08:02 localhost ntpd[28156]: ntpd exiting on signal 15 (Terminated) Oct 13 13:08:31 localhost reg_async[29701]: INFO: sms_net_route_n_rules_add_n_del: Executing: /bin/bash -c 'while ip rule delete table tethMa 2>/dev/null; do :; done; exit 0;' Oct 13 13:08:31 localhost reg_async[29701]: NOTICE: Run: chroot /ddr/aspirin-rootfs-CentOS/ /bin/bash -c 'while ip rule delete table tethMa 2>/dev/null; do :; done; exit 0;' 2>&1 Oct 13 13:08:35 localhost ntpd[5250]: ntpd exiting on signal 15 (Terminated) Oct 13 14:03:44 localhost ddsh: NOTICE: cmd scp -t /ddr/var/releases/ exited with 0: Oct 13 14:05:02 localhost ddsh: NOTICE: MSG-DDSH-00017: autosupport: command "ddboost fc group show detailed" exited with code: 41 Oct 13 14:20:14 localhost ddsh: NOTICE: MSG-DDSH-00017: (tty=pts/0, session=20294) root: command "system upgrade 6.2.1.30-663869.rpm" exited with code: 607 Oct 13 14:24:18 localhost ddsh: NOTICE: MSG-DDSH-00017: (tty=pts/0, session=20294) root: command "system upgrade precheck status" exited with code: 607 The CLI failures can be avoided if the HA peers are set up properly.

Resolution

Verify that the HA pair is properly configured using a CIFS share or NFS export. Check for the following file and remove it: /ddvar/lock/upgrade_lock Restart the update. If the above steps do not address the issue, generate a Support Bundle and open a Technical Support case.
