Now full VV and TPVV volumes are imported in the same way and the local LDs are no longer in writethru. Renamed SNMP MIB definitions file The SNMP MIB definitions file used by HP 3PAR is provided on the release CD as a courtesy for customers that wish to compile the SNMP MIB. The file has been renamed so that the new name matches the 3PAR MIB name named defined in the file. The name has changed from cd1/contents/snmp/3PAR-MIB.mib to ThreeParMIB.mib in the same directory. TOCs more than a day old no longer In HP 3PAR OS version 3.1.1, a check was added when selecting a invalid choice for automatic TOC after system reboot to prevent automatically selecting a TOC selection. more than a day old. this change is reverted. Fixed partial page data inconsistency Under certain conditions, if a node goes down, and an rw snapshot issue for rw snapshots with zero tte with zero detect enabled has a partial page write in progress, the rest of the page could get corrupted with data from the parent of the rw snapshot instead of being set to zero. Fixed node down recovery to handle this situation properly. Support for RW snapshots from RW Read write snapshots can now directly be created from Read write bases bases or other read-write snapshots. This process will not require an explicit read-only snapshot creation in the middle. createsvgroup/createvvset: support creategroupsv now supports creation of RW snapshots from RW bases for RW snapshots from RW bases (or snapshots), instead of only from RO snapshots. Fixed BBU events at insert; a regression caused by 64033 Fix for bug 64033 broke basic assumption that BBU perm. failure is always cleared before I2C faults (if any). That caused NEMOE to send same event twice when BBU monitor cleared any I2C event leaving TPD in inconsistent state with one unresolved event. Added fix to ignore I2C events for first 10 seconds and made sure that NEMOE always sends two distinct events when an I2C error to BBU is cleared. HP 3PAR system can become unavailable during intial sync of large volumes An issue which may cause an HP 3PAR system to become unavailable during the initial sync of volumes greater than 400GB has been fixed. Enhance Node Rescue to handle new TPD packages have been enhanced in 3.1.1 and differ in structure 3.1.1 Patches to previous patches. In instances where Node Rescue is being performed with a patch installed on the HP 3PAR system the correct image could not be formed The patch merging process has been enhanced to correctly merge the patches with the base image to create the correct image to be installed on the HP 3PAR system via Node Rescue. IMC still showing RAID0 volumes IMC will display correct raid type for the volumes. If a r6 type volume is created, IMC with the fix in 3.1.2, it will display Raid 6 instead of Raid 0. NODE0 C-S failed. PANIC: tpd: Assertion point: file: drvmain.c, line: 1101 Code was doing an incorrect check on reductive operators for the address range when the address being used was at the end of the xcb bound area. In this case we should only be checking that the 64B destination does not exceed the bounded range instead of using the xcb length. Firmware could become unresponsive Upgraded 1G iSCSI firmware to version 3.0.1.67 in order to address and cause port resets an incorrect bitmask check that could result in port reset due to loss of response from the firmware. Additional functionality within the createsv command. During the migration of remote copy volumes using peer motion, the need arose to create identical snapshots on the primary and secondary 12 HP 3PAR OS 3.1.2 GA Release Notes
