[ovirt-users] Re: can not add Storage Domain using offload iscsi

Hi, some facts: ovirt-node 4.3.10 (based on Centos 7) hosts are HP blades BL460C with network card supporting iscsi HBA (there are no iscsi nics visible on OS level, but i had to configure ip addresses manually since they were not inherited from BIOS ) # iscsiadm -m iface default tcp,<empty>,<empty>,<empty>,<empty> iser iser,<empty>,<empty>,<empty>,<empty> be2iscsi.c4:34:6b:b3:85:75.ipv4.0 be2iscsi,c4:34:6b:b3:85:75,172.40.2.21,<empty>,iqn.1990-07.com.emulex:ovirt1worker1 be2iscsi.c4:34:6b:b3:85:75.ipv6.0 be2iscsi,c4:34:6b:b3:85:75,<empty>,<empty>,iqn.1990-07.com.emulex:ovirt1worker1 be2iscsi.c4:34:6b:b3:85:71.ipv6.0 be2iscsi,c4:34:6b:b3:85:71,<empty>,<empty>,iqn.1990-07.com.emulex:ovirt1worker1 be2iscsi.c4:34:6b:b3:85:71.ipv4.0 be2iscsi,c4:34:6b:b3:85:71,172.40.1.21,<empty>,iqn.1990-07.com.emulex:ovirt1worker1 # iscsiadm -m session be2iscsi: [1] 172.40.2.1:3260,12 iqn.1992-04.com.emc:cx.ckm00143501947.a0 (non-flash) be2iscsi: [2] 172.40.2.2:3260,6 iqn.1992-04.com.emc:cx.ckm00143501947.b1 (non-flash) be2iscsi: [5] 172.40.1.1:3260,5 iqn.1992-04.com.emc:cx.ckm00143501947.a1 (non-flash) be2iscsi: [6] 172.40.1.2:3260,4 iqn.1992-04.com.emc:cx.ckm00143501947.b0 (non-flash) [root@worker1 ~]# multipath -l 3600601604a003a00ee4b8ec05aa5ec11 dm-47 DGC ,VRAID size=100G features='2 queue_if_no_path retain_attached_hw_handler' hwhandler='1 alua' wp=rw |-+- policy='service-time 0' prio=0 status=active | |- 3:0:2:1 sds 65:32 active undef running | `- 4:0:0:1 sdo 8:224 active undef running `-+- policy='service-time 0' prio=0 status=enabled |- 3:0:3:1 sdu 65:64 active undef running `- 4:0:1:1 sdq 65:0 active undef running ... target SAN storage is detected, and exposed LUNs are visible. I can even partition them, create filesystem and mount them in OS, all when doing manually step by step. when trying to add Storage Domain in iscsi the LUNs/targets are nicely visible in GUI, buf after choosing a LUN the domain becomes locked and finally enters detatched mode. can not attach the Datacenter. in engine.log similar entry for each host: 2022-03-16 22:27:40,736+01 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.ConnectStorageServerVDSCommand] (EE-ManagedThreadFactory-engine-Thread-1111) [e8778752-1bc1-4ba9-b9c0-ce651d35d824] START, ConnectStorageServerVDSCommand(HostName = worker1, StorageServerConnectionManagementVDSParameters:{hostId='d009f919-b817-4220-874e-edb0e072faa1', storagePoolId='00000000-0000-0000-0000-000000000000', storageType='ISCSI', connectionList='[StorageServerConnections:{id='4dd97e5d-c162-4997-8eda-3d8881c44e31', connection='172.40.1.2', iqn='iqn.1992-04.com.emc:cx.ckm00143501947.b0', vfsType='null', mountOptions='null', nfsVersion='null', nfsRetrans='null', nfsTimeo='null', iface='null', netIfaceName='null'}, StorageServerConnections:{id='6e52a5bb-0157-4cbe-baa3-cfc8001d35b2', connection='172.40.2.1', iqn='iqn.1992-04.com.emc:cx.ckm00143501947.a0', vfsType='null', mountOptions='null', nfsVersion='null', nfsRetrans='null', nfsTimeo='null', iface='null', netIfaceName='null'}, StorageServerConnecti ons:{id='87194270-bb0e-49d8-9700-17436f2a3e28', connection='172.40.1.1', iqn='iqn.1992-04.com.emc:cx.ckm00143501947.a1', vfsType='null', mountOptions='null', nfsVersion='null', nfsRetrans='null', nfsTimeo='null', iface='null', netIfaceName='null'}, StorageServerConnections:{id='ef8e2fbd-cbf6-45e9-8e83-f85a50001c2d', connection='172.40.2.2', iqn='iqn.1992-04.com.emc:cx.ckm00143501947.b1', vfsType='null', mountOptions='null', nfsVersion='null', nfsRetrans='null', nfsTimeo='null', iface='null', netIfaceName='null'}]', sendNetworkEventOnFailure='true'}), log id: 317c3ffd ... 2022-03-16 22:30:40,836+01 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.ConnectStorageServerVDSCommand] (EE-ManagedThreadFactory-engine-Thread-1111) [e8778752-1bc1-4ba9-b9c0-ce651d35d824] Command 'ConnectStorageServerVDSCommand(HostName = worker1, StorageServerConnectionManagementVDSParameters:{hostId='d009f919-b817-4220-874e-edb0e072faa1', storagePoolId='00000000-0000-0000-0000-000000000000', storageType='ISCSI', connectionList='[StorageServerConnections:{id='4dd97e5d-c162-4997-8eda-3d8881c44e31', connection='172.40.1.2', iqn='iqn.1992-04.com.emc:cx.ckm00143501947.b0', vfsType='null', mountOptions='null', nfsVersion='null', nfsRetrans='null', nfsTimeo='null', iface='null', netIfaceName='null'}, StorageServerConnections:{id='6e52a5bb-0157-4cbe-baa3-cfc8001d35b2', connection='172.40.2.1', iqn='iqn.1992-04.com.emc:cx.ckm00143501947.a0', vfsType='null', mountOptions='null', nfsVersion='null', nfsRetrans='null', nfsTimeo='null', iface='null', netIfaceName='null'}, StorageServerConnec tions:{id='87194270-bb0e-49d8-9700-17436f2a3e28', connection='172.40.1.1', iqn='iqn.1992-04.com.emc:cx.ckm00143501947.a1', vfsType='null', mountOptions='null', nfsVersion='null', nfsRetrans='null', nfsTimeo='null', iface='null', netIfaceName='null'}, StorageServerConnections:{id='ef8e2fbd-cbf6-45e9-8e83-f85a50001c2d', connection='172.40.2.2', iqn='iqn.1992-04.com.emc:cx.ckm00143501947.b1', vfsType='null', mountOptions='null', nfsVersion='null', nfsRetrans='null', nfsTimeo='null', iface='null', netIfaceName='null'}]', sendNetworkEventOnFailure='true'})' execution failed: VDSGenericException: VDSNetworkException: Message timeout which can be caused by communication issues how to make it working? I read offload iscsi is supported but all the documentation i found is for software iscsi. any hints welcomed thanks _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/GJKBZO6VZ4S...
