Issue ID Item Description device entry, thus the follow-up operations (e.g. LOGO) caused a host being wrongly disconnected. 78498 Sysmgr Unresponsive Fixed a defect in the sysmgr subsystem that could cause the sysmgr to be unresponsive and for host io to be blocked. Operations involving a region move (such as tunes) or a node integration could get the sysmgr into this state. Fixed the race condition between the sysmgr and kernel that caused this behavior. 78568 Correct handling of P10000 ASIC hardware errors In earlier versions of HP 3PAR OS for P10000 systems, a node was allowed to continue operating despite experiencing certain hardware errors internal to its ASIC device. This deficiency has now been addressed. When a node encounters any hardware error in an ASIC device, it is rebooted. 78639 Host lost access during HP 3PAR OS The ioctl to non-existant nodes has been removed in 3.1.2, this ioctl upgrade from 3.1.1 MU1 to 3.1.1 will only be sent to nodes whic are online. MU2 78761 int coal is still enabled in 3.1.2.220 The default interrupt coalescing stance for FC ports has been changed as follows: 1. Target ports will come up with interrupt coalescing disabled across a 3.1.1->3.1.2 update. 2. All new target ports created will have interrupt coalescing disabled. 79944 Handle abort of pending NACA commands Due to a software error in earlier versions of HP 3PAR OS, abort of commands which trigger the ACA ACTIVE condition was not handled correctly. Under rare circumstances, this could cause node panics on busy systems to which AIX hosts were attached. The software error has been fixed in this release. Known Issues with the OS Issue ID 54303 55097 60162 60936 Item Description Emulex-based 8Gb HBAs fill word compatibility The Emulex-based 8Gb HBAs use a different fill word (ARB(FF)) for Fibre Channel connections. The Fibre Channel switch port connecting the Emulex-based 8Gb HBAs fill word compatibility 54303 8Gb HBA port must have the same fill word configured for compatibility. Contact the switch vendor for help to configure the fill word. On Brocade switches, the command to configure the fill word is portcfgfillword. Need to disable UAC if libtls cannot load On Windows 7 or Vista systems, if this error is encountered: C:\Users\cli>cli -sockssl system: s238 user: a username password: Could not open connection to CLI server process on ""s238"": -sockssl option not supported, libtls not loaded. System name may be invalid, or the process may not have started yet or may have failed. Disable the UAC feature and run the libtls command again. Afterwards, turn on the UAC if needed. Remote Copy Link Speeds RCFC link issues when ISLs are removed. When setting link speeds for Remote Copy operations using the controlport command speed setting, only the 1000Mbps link speed option should be used. Using the 10Mbps and 100Mbps link speed options may result in negotiation issues. Support for setting the interface speed to 10Mbps and 100MBps will be removed in a future release. Under heavy remote copy traffic, adding or removing an ISL to the fabric may cause traffic delays and congestion, due to the dropping of FC frames. FC fabrics with multiple ISL connections should be configured with these links trunked together. Known Issues with the OS 15
