Hi there,
I installed two StoreServ 7200 with HP this week and Peer Persistence is working but only under certain circumstances :
During our tests we’ve been able to make a transparent switchover but it worked only the second try after an ESXi reboot (ESXi 5.1 Patch 1 Build 914609). The first time it only freezes and never reconnect.
HP said it was a known issue and we only had to reboot the ESXi once and that all the subsequently exported 3PAR Volumes will be able to switchover afterward.
I can’t find any explanation of why a reboot is needed and how I can check if it’s OK and if it WILL be able to switchover.
What I see from a VMware point of view is that during a switchover, the old Optimized paths stay optimized (AO) instead of transitioning to STANDBY :
- Normal operation : {TPG_id=258,TPG_state=STBY}{TPG_id=256,TPG_state=AO}
- During freeze : {TPG_id=258,TPG_state=AO}{TPG_id=256,TPG_state=AO}
- Switched over : {TPG_id=258,TPG_state=AO}{TPG_id=256,TPG_state=STDBY}
All prerequisites are met (vSphere 5.1 Patch 1, inform 3.1.2 MU3, same WWN and LUN ID for volumes, Persona 11, Qfull, Custom Claim rule …)
I hope that someone will be able to help me.
Thank you in advance.
