When running AO, ensure that each region move task starts at least 3 minutes apart in order to avoid the scenario where region moves complete close together.
Issue ID Item Description 96827 During persistent port failover, During persistent port failover, multiple nodes could give error and multiple nodes could give error and reboot due to a large number of SCSI command retry messages which reboot. overload the event handling mechanism. This is resolved by ensuring that the VLUNs are exported before allowing the failover to proceed.
Issue ID Item Description 99429 Node1 reboots with a Linux "Oops" Node1 reboots with a Linux "Oops" message due to insufficient message due to insufficient interrupt interrupt stack size. This is resolved by increasing the size of interrupt stack size. stack in Linux to 32 KBytes. 99549 If the AutoExportAfterReboot parameter is set to no and setsysmgr is not used to export LUNs after a reboot, the LUNs might be exported if a host is reconnected after the system reboot.
Issue ID Item Description might enter in config_wait state intermittently. replaced, the iSCSI port might intermittently come up in config_wait state following node reboot or node error. Resetting the port clears the config_wait state. To resolve the inconsistency in the TOC, switch the port to FCoE mode and then back to iSCSI mode.
2 HP 3PAR CLI Release Notes Installation Notes for the CLI Virus Checking Virus checking is known to slow down and potentially cause issues with installation of the CLI. Before attempting an install or uninstall of the OS CLI, shut down all running applications and disable virus-checking software.

This means: • From one chunk to the next, the columns can be wider, if the names or values are wider. • If the output is sorted, it is sorted within each chunk. This means that the VV zzzz, may appear at the end of the first chunk but not at the end of the last chunk. The total lines will remain the same. This is the same as the command setclienv histstatnum. For more information, see the command setclienv -h. An option -sortcol is added to some CLI commands.
Command Options added (unless stated otherwise) setqos setrcopygroup new policy [path_management | no_path_management] setsched -f and schedule burst detection setsys ThermalShutdown NOTE: The default value is on. When this is set to off, thermal shutdown is turned off but individual drives will continue to be spun down whenever their thermal limits are reached. To turn the thermal shutdown functionality on, set the value to on.
Command Options added (unless stated otherwise) srstatvlun -sortcol, -btsecs defaults changed srvvspace -sortcol, -btsecs defaults changed startao -min_iops statqos waittask Removed and Deprecated Commands and Options The following commands are removed or deprecated in the OS 3.1.3 release.
