Simulate SAN storage interruption
Hi ,
I'd like to test HA when a connection to the SAN to one of the Hypervisors interrupted .How to simulate SAN external storage disconnection in command line ?
In the RHEV documentation there is an axample with ifdown command for ISCSI strorage only .
/Vlad.

There are multiple approaches (all are dependent upon SAN vendors):
1) via the SAN fabric-switch cli (block the ports which provide half the paths, then after certain interval unblock them).
2) power-off the counterpart SAN Switch in a redundant config (again via the cli of SAN fabric-switch, which, unfortunately, is vendor specific).
3) If the host HBA is connected to some layer-1 switches like APCON or MRV, then you can use the CLI of APCON (or MRV) to simulate HBA port failures/blockages.
Hope it helps.
