Storage Controller Flap on SAN

Wednesday, January 4th, 2012

Update 13:50
Dell have identified an issue that may have caused the controller crashes pertaining to VMware ESXi’s handling of iSCSI hardware acceleration. There is no resolution for the bug in the most recent EqualLogic firmware, but Dell have identified a workaround that we can implement on our servers. This is presently being enacted; a further update will be given when this has been completed

Update 12:33
For now we have stabilised the system by disabling the redundant port. Customers should still consider themselves at risk at this time whilst we continue to investigate the matter with our supplier.

Dear Customers

We have observed a problem with our SAN storage in Bournemouth where by our controller had begun failing over its primary 10Gbit ports. This started at 11:43 and persisted until 12:00. The system then became stable and we have checked error logs etc. Upon inspection the controller has logged no reason for it doing this so we have immediately raised a support ticket with our supplier.

The system has now again just started failing over its ports at 12:15.

This will be causing disruption to VDS customers hosted on this infrastructure as well as some storage customers.

We will update this post as soon as we have further information.

*** Resolved *** C4L Network Stability Issues

Update 00:51: We have resolved the issues and have found the root cause of the problem. We will be sharing this with affected customers later today.

Dear Customers,

We are aware of an issue affecting the stability of the network at this time. We are looking into this and will update you shortly.

*** Resolved *** DNS Issue

Thursday, December 29th, 2011

Dear Customers,

Earlier we had an issue with our primary DNS server, 84.45.112.20. This has now been resolved and normal service has been resumed. The alternate server, 82.197.83.198 was unaffected during this time.

C4L apologise for any inconvenience.
