SRR (Simplified Remote Restart) - Overview

• PowerVM Remote Restart is not a replacement for PowerHA, which is an application

clustering solution and has a much faster recovery time objective than Remote Restart.

• The Remote Restart solution requires that the VM is rebooted on the new server, the file

systems are checked, and the application recovers just like if you had a power failure. These

steps are much longer than a PowerHA.

• Unlike Live Partition Mobility (LPM), the partition is restarted on target system which results

in downtime for the applications. LPM cannot be used in this situation since the source

system is down.

• There are two types of Remote Restart

o Legacy Remote Restart with Reserved Storage Device Introduced in Power 7 & supported with HMC V8R8.1.0 & 760 firmware or later

o Simplified Remote RestartDeviceIntroduced in Power 8 with firmware 820 , HMC V8R8.2.0 & VIOS 2.2.3.4.

SRR (Simplified Remote Restart) - Notes

• If user performs any configuration change without going through the HMC interface, like

attaching storage through VIOS CLI, refdev command should be run for the particula

client partition on the HMC

• refdev command refreshes the partition/profile configuration data persistend to HMC

• Partition must be activated at-least once before remote restart can be performed.

SRR (Simplified Remote Restart) – Command Line Interface


• Remote Restart Validate

rrstartlpar -o validate -m managed-system -t target-managed-system {-p partition-name | --id partition-ID}

• Remote Restart

rrstartlpar -o restart -m managed-system -t target-managed-system {-p partition-name | --id partition-ID}

• Remote Restart with latest available configuration

rrstartlpar -o restart -m managed-system -t target-managed-system {-p partition-name | --id partition-ID --usecurrdata

• Remote Restart Abort (Canceling a remote restart operatin which is in progress)

rrstartlpar -o cancel -m managed-system -t target-managed-system {-p partition-name | --id partition-ID}

• Remote Restart Recover (Recover from a failed restart operation)

rrstartlpar -o recover -m managed-system -t target-managed-system {-p partition-name | --id partition-ID} [--force]

• Remote Restart Cleanup (On source server after successful remote restart)

rrstartlpar -o recover -m managed-system -t target-managed-system {-p partition-name | --id partition-ID} [--force]

Auto Cleanup

• Auto Cleanup of a remote restarted partition on source system is performed when

o Source system state comes back to operating state

o Partition remote restart status is “Remote Restarted”

o RMC for the VIOS partitions serving the clients is active

• Auto Cleanup is done without force option which means if there is any failure in the auto cleanup like

server adapter for a client adapter is not found or RMC command sent to the VIOS fails, then the

cleanup would fail and leave the LPAR on the source system with remote restart status of “Source

Side Cleanup Failed”.

• User can trigger the manual cleanup using the rrstartlpar command

• When PowerVC is used to orchestrate Remote Restart

o Auto cleanup can be disabled (by default, auto cleanup is enabled)

o Setting is maintained across upgrades, but not on fresh install.

o CLI :

rrstartlpar –o set -r mc –i “auto_cleanup_enabled=0|1”

lsrrstartlpar –r mc
