Hi All, We wish to create some kind of DR plan for our OVM 4.4.10.7-1.0.22.el8 environment. Idea is to do storage replication of defined Storage Domains. steps: create LUN on storage present LUN to OVM create Storage Domain put VMs on Storage Domain on storage replicate LUN to another storage [or the same storage] Storage Domains contains OVF_STORE Now, recovery On live OVM present replica of LUN import Storage Domain But we cannot import replica LUN. Where to look for errors? Is this action possible it all? Facts OVM is the same version Storage is the same vendor LUN is browsable on SAN level and have differen WWIN, if we wish to add replicated LUN like new Storage Domain. Adding new Storage Domain mean that LUN will be formatted ... What I do wrong?
Hi, I believe that when you replicate the LUN using Array Storage, *you also replicate the uuid of the lvm* (volume group) that oVirt/Linux uses. I believe this is the cause of not being able to import the new LUN as Domain Storage. You can view the logs on the host you chose to import the LUN (rescan process). The file is located in */var/log/vdsm/vdsm.log*. *My suggestion:* 1 - Create a new LUN 2 - Create a Domain Storage 3 - Replicate the data (disks) using some script or backup software such as Vinchin Cheers!

Hello Jorge, Thank you for your answer, but it seems that during the import process oVirt cannot read or see the contents of the LUN Logs say's 2023-12-27 20:36:20,608+01 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.GetDeviceListVDSCommand] (default task-15) [cabf0419-622d-40a9-ab65-398b7146fbbf] FINISH, GetDeviceListVDSCommand, return: [LUNs:{id='36005076810810557b80000000000001a', physicalVolumeId='6NQ6wQ-EMGL-VVP9-BxaG-ZzEr-jtR1-kjCHtJ', volumeGroupId='Sts0sX-FVC4-J6KX-Zs1W-bt42-M5nO-uO12oK', serial='SIBM_2145_0204204155eeXX00', lunMapping='2', vendorId='IBM', productId='2145', lunConnections='[]', deviceSize='200', pvSize='199', peCount='null', peAllocatedCount='null', vendorName='IBM', pathsDictionary='[sde=true, sdh=true, sdk=true, sdn=true]', pathsCapacity='[sde=200, sdh=200, sdk=200, sdn=200]', lunType='FCP', status='Unknown', diskId='null', diskAlias='null', storageDomainId='null', storageDomainName='null', discardMaxSize='0'}, LUNs:{id='36005076810810557b80000000000001f', physicalVolumeId='', volumeGroupId='', serial='SIBM_2145_0204204155eeXX00', lunMapping='0', vendorId='IBM', productId='2145', lunConnections='[]', deviceSize='100', pvSize='0', peCount='null', peAllocatedCount='null', vendorName='IBM', pathsDictionary='[sdc=true, sdf=true, sdi=true, sdl=true]', pathsCapacity='[sdc=100, sdf=100, sdi=100, sdl=100]', lunType='FCP', status='Unknown', diskId='null', diskAlias='null', storageDomainId='null', storageDomainName='null', discardMaxSize='0'}, LUNs:{id='36005076810810557b800000000000019', physicalVolumeId='uYkUnL-Osm1-HdZ2-YLtz-JVsb-hgAs-RPgV3D', volumeGroupId='3O9rkv-54T9-jiXT-Qyrg-DWl2-z8nL-vHFCIj', serial='SIBM_2145_0204204155eeXX00', lunMapping='1', vendorId='IBM', productId='2145', lunConnections='[]', deviceSize='100', pvSize='99', peCount='null', peAllocatedCount='null', vendorName='IBM', pathsDictionary='[sdd=true, sdg=true, sdj=true, sdm=true]', pathsCapacity='[sdd=100, sdg=100, sdj=100, sdm=100]', lunType='FCP', status='Unknown', diskId='null', diskAlias='null', storageDomainId='null', storageDomainName='null', discardMaxSize='0'}], log id: 6c0b131d First LUN is hosted engine LUN The second LUN is the LUN I am trying to import and it is a clone of the third LUN The third LUN is the LUN I cloned to the second lun from the list The idea is to import the replicated lun in another ovirt cluster ovirtA -> lunA then storage replication of lunA -> lunB replicated lunB import to ovirtB
