Hello to all,

is iscsi supported now on MC Serviceguard?

Best regards, Alfons

No.

Serviceguard requires that all storage I/O initiated from a node that has been ejected from the cluster will be completed or abandoned before any other node can start packages from the ejected node. The error recovery (packet retransmission) built into TCP/IP opens the possibility for I/O from an ejected node to arrive to the storage after other nodes in the cluster have taken ownership of the shared storage for a package, which would result in data corruption, so it cannot be supported today. It will require changes to Serviceguard and HP-UX before this issue can be prevented.

Hi - It appears that HP-UX 11.31 and Serviceguard A.11.20 March 2012 Patch C Release now supports iSCSI

Can we expect iSCSI to be supported with Linux running SG anytime soon?

Thank you
