How to boot VPARs in Single User mode or LVM Maintenance Mode or LVM Quorum override mode with Single User

Note: These apply to VPARs versions 4.x/5.x . For the latest in case of any differences refer to the latest documents on the VPARs


How can we boot a VPAR in various modes?

We can boot a VPAR in a desired mode from the UNIX Prompt using vparboot or using the VPMON vparload command. But the VPAR needs to be down to be booted in a desired mode.


vpar1#vparboot –p vpar2 –o “-is”  : Single user boot

vpar1#vparboot –p vpar2 –o “-lm”   : LVM Maintenance boot

vpar1#vparboot –p vpar2 –o “-lq” –o “-is”   : Single User with the Quorum ignore

From VPMON if we need to do the same things


VPMON

MON>vparload –p vpar2 –o “-is”   : Single user boot

MON>vparload –p vpar2 –o “-lm”   : LVM Maintenance Boot

MON>vparload –p vpar2 –o “-lq” –o “-is” : Single user with Quorum Ignore
