Error - Cannot Detach Scsi Lun


admit I was a little surprised when I found out from EMC that SRM does not support Recoverpoint Point in Time fail over. Funny how VMware couldn't tell me this? They just passed the buck to EMC… typical! What's the point of purchasing a product like EMC Recoverpoint if you cannot use it to its full potential? Well, that's not entirely true, you can, you just have to do it outside of SRM! Maybe SRM 5 has spoilt me a little. It does what it is supposed to do extremely well, but I just assumed the SRM RecoverPoint SRA would integrate with RecoverPoint's image access and allow you to pick a previous point https://kb.vmware.com/kb/2032365 in time if required during a failover. Alas, this is not the case. You cannot pick a point in time with SRM, it always uses the latest image only. This is a feature request for SRM, VMware employees if you are reading this: When I perform a Test Failover I would like the ability to pick a previous point in time if required, before the failover commences. What if you have to performed a Disaster Recovery https://blocksandbytes.com/category/srm/ failover and your latest image is corrupt. How do you then roll back to a previous journal entry in your Recovery Site? These are some of the scenarios I don't quite fully understand and I'm going to do some testing to see if I can combine some SRM and RP steps to at least partially automate the process - the thought of using RP natively, enabling image access,  mounting LUNS in the recovery site, rescanning hosts, registering VMs in vCenter, etc has really put me off using RecoverPoint's point in time features. More on this to follow. 2 Comments Posted in RecoverPoint, SRM Tagged failover, point in time, recoverpoint, restore, srm What to do if a reprotect fails in SRM… Protection group has protected VMs with placeholders which need to berepaired Posted by blocksandbytes on August 2, 2012 I had this issue today where a reprotect failed after a Planned Migration. I thought it was worth running through what I had to do to resolve the issue without performing a ‘Force Cleanup' Reprotect as there is currently no KB article describing this workaround. In my case the planned migration went ahead as planned without issues. All VMs were powered on at the Recovery Site and the Recovery Plan completed successfully. When it came to the reprotect however, the reprotect failed on Step 3

LUN's to vmware before crashing and leaving vmware with a large amount of dead LUN's it could not connect to. Cue a rescan all … and everthing started crashing ! Our primary cluster of 6 servers started to abend, half the ESX servers decided to vmotion of every vm and shutdown, the other 3 ESX servers were left running 6 servers worth of vm's, DRS decided to keep moving vm's of the highest utilised ESX server resulting in another esx server becoming highest utilised which then decided to migrate all vm's of and so on in a never-ending loop As a result the ESX servers were: unresponsive showing powered of machines as being on unable to vmotion vm's of intermittently lost connection to VC lost vm's that were vmotioned i.e. the vms became orphaned Here's what i did to fix the issue. 1 – get NAA ID of the lun to be removed  See error messages on server Or see properties of Datastore in vc (assuming vc isn’t crashed) Or from command line : #esxcli storage vmfs extent list Alternatively you could use #esxclu storage filesystem list however that wouldn’t work in this case since there were no filesystems on the failed luns e.g. output Volume Name VMFS UUID                           Extent Number Device Name                           Partition ------- ----------------------- --------- ------------------------  ------ datastore1  4de4cb24-4cff750f-85f5-0019b9f1ecf6             0  naa.6001c230d8abfe000ff76c198ddbc13e        3 Storage2    4c5fbff6-f4069088-af4f-0019b9f1ecf4             0  naa.6001c230d8abfe000ff76c2e7384fc9a        1 Storage4    4c5fc023-ea0d4203-8517-0019b9f1ecf4             0  naa.6001c230d8abfe000ff76c51486715db        1
