Hi all,
Was hoping someone may have seen the problem we have encountered over the last 2 weeks.
Our VMs are performing unexpected shutdowns. Our Exchange server has rebooted twice today 
The timing of the shutdown matches with information we are seeing our Equallogic logs:
INFO 26/07/2013 9:35:19 AM APCEQLM1 7.2.15 | 7.2.24 | 7.2.29 iSCSI session to target '192.168.43.12:3260, iqn.2001-05.com.equallogic:4-52aed6-c7ca4349e-87b00217be35059e-lon-prod-vm-1' from initiator '192.168.43.31:58797, iqn.1998-01.com.vmware:apcesxhost1-24c73c18' was closed. | iSCSI initiator connection failure. | No response on connection for 6 seconds.
We have 1 Equallogic PS4100X, running the latest EQL firmware 6.0.5. We have 2 stacked Powerconnect 6224 switches. Our array and switches were configured by DELL support.
We have followed DELL recommendations on connecting vSphere to ISCSI storage. As far as I can see our vSwitches are configured correctly.
Anyone have any ideas why we're seeing this behavior ? I've logged this with DELL support but thought I'd ask on the forums in case anyone has experience this issues.
Thanks in advance!
Lee
