AMU

Improvements

PR128 'Frozen' command queue.

There can be a situation (not often) when the AMU command queue hangs. In

this state AMU accepts the commands (from host or DAS) but does't issue any

command for robot. This state can be as long as 15 minutes. Fixed in

AMU3.11H2

PR129 HOC tcp/ip sockets leak. Under some customer configurations

PR130 Trap in BUD module. When there is no available socket (see PR129), BUD can

trap on allocating the new connection. Fixed in AMU3.11H1

PR131 'Hanged' KEEPs. Under some conditions (MOUNT, pending KEEP and

cleaning combination) the pending keep can 'hang'. Fixed in AMU3.11H1

PR132 HOC AMU-to-AMU connection.

There was an error in AMU-to-AMU connection. It accepted only ABBA/2

commands. If the link from active AMU to host is lost, then AMU-to-AMU link

would be used to transfer ABBA/1 commands. In this case these commands

can be corrupted during the transfer. Fixed in AMU3.11H5

PR133 Error when accessing DCI drives on systems with more then 1 DCI unit. Fixed

in AMU3.11H1

PR135 There was an error in installation script of AMU3.11. It led to inability to update

database binding during upgrade and requires a manual intervention.

PR150 Thread leaking in Dual-AMU in some wrong configurations

PR153 Trap in AMU GUI when in drive's description is entered with more then 30

chars.

PR155 ACOM shows the incorrect status of AMU/AMU connection when active AMU

was shut down

PR159 Sometimes AMU closes with error at the time of changing parameters for

interfaces.

PR181 Service - Dual-AMU: Option Activate this AMU doesn't work

PR192 Switching between AMUs should not be allowed if switch on ADS is in a

position different from AUTO.

Related Ticket Explanation of Changes

PR120 Installation script should check for active AMU/DAS during installation/upgrade

process and terminate upgrade if necessary

PR133 Improved configuration handling for CanLib.

On some customer configurations there are some non-DCI type drives

connected to the DCI unit. This fix is a wrap-around for such configurations.

Fixed in AMU3.11H1

PR142 Support of LTO-2 FibreChannel drives (as DCI-connected).

The FibreChannel-related parameters should be set from AMU GUI (FC AL

address, WorldWideName). Also FC-related information should be available in

AMU GUI (FC Status etc.)

PR151 Some improvement for BUD
