(just now was committed when I wrote mail) What's new? (from 20090323) o starting to support multipath I/O by VMware ESXi (Fix/MRU/RR) o wildcard address listen and translate IP (useful on DHCP) o utilization efficiency of the command queuing was improved o task abort handling in cluster nodes o reduce deadlock and timeout risk (from 20090314) o support command queuing o shrink pre-allocated SCSI sense data buffer from 64K to 4K. o allow full specify "eui." and "naa." like "iqn." o if small PDU, write as one buffer. and many bug fixes The command queuing is disabled by default. If you want to use it, please add QueueDepth key in the LogicalUnit section of your configuration. for example: [LogicalUnit1] # Queuing 0=disabled, 1-255=enabled with specified depth. QueueDepth 16 If you have any problem with command queuing, comment out or specify 0 to disable it. Disabled version is about the same behavior as 20090314. To use wildcard address, edit your configuration like this: [PortalGroup1] # for IPv6 Portal DA1 [::]:3260 # for IPv4 Portal DA1 0.0.0.0:3260 Do not use mix with other IPs. After this change you can see TargetAddress as connected IP. IP address family connected by discovery session is important. If you need IPv6 target address, should use IPv6 in discovery. Also if you need IPv4 target address, should use IPv4. The istgt will reply only one IP address of multiple wildcard address to the initiator. Here is release 20090326: http://shell.peach.ne.jp/aoyama/archives/386 -- Daisuke Aoyama
