Disks or devices whose size is greater than 1 TB and less than 2 TB are supported only on OpenVMS Version 8.4 on both Integrity servers and Alpha architectures. To support defragment disks of size up to 2 TB, the following is changed: - The design is changed to use unsigned integer datatypes for holding the LBN, VBN, and size related variables. Also, the code logic to compare these unsigned variables is modified. With this new design, DFO can defragment disk capacities greater than 1 TB which was not possible in the earlier versions. 5 Problems Fixed in DFO Version 3.1 The following problem is fixed in this release of DFO: - While installing DFO version T3.1 on an Integrity server with Performance Solution Data Collector(PSDC), it displays the following error message: %DCL-W-UNDSYM, undefined symbol - check validity and spelling \PSDC_VERSION\ %DCL-W-UNDSYM, undefined symbol - check validity and spelling %VMSINSTAL-E-INSFAIL, The installation of DFGT V3.1 has failed This problem is fixed in this release. 4 6 Known Problems and Restrictions This section describes known problems and restrictions for Version 3.1 Known problem o Under some conditions, defragmenting a file of size more than 500 GB on a volume of size greater than 1 TB, the following bugcheck might occur: 'PTRCNT, ACP block count exceeds retrieval pointer size' This has been root caused to a File System issue. A File System patch is under development and is expected in Q2 of calendar year 2012. Please contact HP support representative for the availability of an OpenVMS File System patch containing the fix for this problem. 5
