Hello oVirt Community!
Need help in configuring iSCSI DataCenter on oVirt.
I have HP P4000 iSCSI Storage (LeftHand). And LUN on it. This LUN is
available for the Server.
I tried to install oVirt from ovirt-dre repo. Everything works except
adding iSCSI Storage Domain.
After iSCSI-discovery i get list of iSCSI LUNs. But I get error after
choosing LUN I need (Error#1).
If I try to add it second time I get another errors (Error#2 or Error#3).
If I operate with iSCSI volume manually, I have no problems - Partitions
are created.
Can you advise something? I stuck with this problem for two weeks already...
First I installed ovirt3.1. This week ovirt3.2 released and I did a
fresh installation of this version, but nothing changed - errors are the
same.
*Error #1:*
Error while executing action New SAN Storage Domain: Cannot create
Logical Volume
*Error #2:*
Error while executing action New SAN Storage Domain: Physical device
initialization failed. Check that the device is empty. Please remove all
files and partitions from the device.
*Error #3:*
Error while executing action New SAN Storage Domain: Invalid physical device
