Anyone else loosing iSCSI targets when replicating?
We have 2 SANs and we are using asyncronous replication to push our data to our second unit at night. Also we are using IETD instead of SCST, see my previous post as to why. Yet when we replicate it now that we transitioned to VMware from Virtual Iron, it drops the targets and all guests crash. I have to reset the iSCSI connections to get it back up. What is going on? I have not been able to replicate for some time now, and this is creating a huge hole in our DR plan. From everything I understand this should be a fully supported operation by both VMware and Open-E.
Sure we can try Syncronous. We have a 100Mb pipe that we use between here and our remote site. I'll try that out. We are on version 4550, but I'll be updating to the latest tonight. 2 of our Targets are Block-IO, but as mentioned in my other thread, we are still stuck on IETD. But I'll be trying that out tonight as well.
Yes the pipe is shared. However, we have always been able to max out the available bandwidth, up to 14MB in bursts. We'll see after I do some testing tonight!
Well when I tried Syncronous last night it did not see to drop the iSCSI connections. However, the router we have still went down. We never could figure out what it was about the replication that started taking it down.
