Upgrade failure recovery on Linux

operating system

Use install.sh command in the new OMPC version package to do upgrade or install OMPC. The

install.sh command detects the version of OMPC. if there is an old version installed, upgrade process

is initialized. If not, then a new version is installed.

NOTE: If you use rpm -U during the Dell OpenManage Power Center installation or upgrade, many

warning messages will get displayed. You can ignore these warning messages as the upgrade

operation will continue as expected. To resolve this issue, it is recommended that you use

install.sh instead of rpm -U.

Check OMPC status

If the installer process is stopped or server is switched off during upgrade, the upgrade fails. Follow the

steps to troubleshoot the upgrade failure scenario:

1. Run rpm –q OpenManage_PowerCenter command on the command line interface to get the

current version OMPC.

2. If the OMPC old version is displayed, for example 3.1.0.XXXX, it means OMPC upgrade operation has

not been started, see Recover OMPC section.

3. If the OMPC new version is displayed, for example “3.2.0.XXXX”, it means OMPC upgrade has been

started, see Check OMPC database daemon status section.

4. If neither old nor new version is displayed, see Rollback to previous OMPC version section.

5. See OMPC database upgrade status to view the upgrade status.

Recover OMPC

1. Copy any files in /etc/ompc/backup/[OMPCFODLER] back to the [InstDir] with the same folder

structure: cp –rf /etc/ompc/backup/[OMPCFODLER] [InstDir].

2. Move the backup pgdata folder (e.g. /opt/dell/pgdatabak) back to [InstDir], rename it to the original

name (e.g. pgdata) if changed.

rm -r -f /opt/dell/ompc/pgdata

and

mv -f /opt/dell/pgdatabak /opt/dell/ompc/pgdata

3. Run the [InstDir]/startup.sh command to start the old OMPC daemons.

4. Remove /etc/ompc if they exist.

Check OMPC database daemon status

Check if the file upgradeok exists in /etc/ompc. If yes, it means that the upgrade is completed

successfully. If not, run

[InstDir]/ompcstatus command to check OMPC database daemon status.
