CAM Target Layer (CTL), when originally developed by + Copan/SGI, had support for High Availability clustering. + Unfortunately, significant portions of the HA code were never + published with the main body of the source code. Now, the missing + part has been reimplemented from scratch and fixed/improved.

+ +

This code supports dual-node HA with Asynchronous LUN Unit + Access (ALUA) in four modes:

+ + + +

In the case of lost interlink connectivity to primary node, + the secondary node falls into the Transitioning state, which is + like Unavailable and can't answer most requests, but makes the + initiator wait for recovery or cluster failover.

+ +

CTL also got a large number of other improvements, including + support for emulation of CD/DVD drives and removable disks, + live LUN reconfiguration, etc.

+ +

The code is committed to &os; head and was recently merged to + stable/10 branch. +
