Hi,

Situation:

iSCSI Failover with two DSS and Storage Replication.
Connected to two VMware ESXi 4 Servers.

Secondary/Passive Node have a damaged RAID Harddisk (RAID5) and I replaced it.
The controller (LSI) is now doing the RAID REBUILD (copyback) proccess.

I started the Secondary/Passive, checked the Storage Replication (was ok) and started the Failover Service.

In this moment my Windows 2003 virtual machines lost the connection to their SCSI drives and I was not able to browse the Storage from ESXi. VMware does not lost the connection to the Virtual iSCSI IP, only the Storage was not accessable.

Now I stopped Secondary/Passive again and opend the RAID GUI. I will wait now until the reboot is finished before starting Open-E again.



Questions:

1. Is this only a performance issue when Sec./Pass. is doing a RAID Rebuild (LSI Hardware Controller)? Why does this have an impact to Primary/Active Node?

2. When I keep Sec/Pass offline for 1-2 Days until the rebuild is done - what is the best way to start it again?

- Start Open-E
- Start Volume Replication and wait until it's constistent
- Start Failover Service ?



Best Regards,
Manuel
