SUMMARY OF KNOWN ISSUES: ----------------------------------------- NONE KNOWN ISSUES : -------------- NONE FIXED INCIDENTS: ---------------- PATCH ID:6.0.500.000 * INCIDENT NO:3408321 TRACKING ID:3408320 SYMPTOM: Thin reclamation fails for EMC 5875 arrays with the following message: # vxdisk reclaim Reclaiming thin storage on: Disk : Reclaim Partially Done. Device Busy. DESCRIPTION: As a result of recent changes in EMC Microcode 5875, Thin Reclamation for EMC 5875 arrays fails because reclaim request length exceeds the maximum "write_same" length supported by the array. RESOLUTION: The code has been modified to correctly set the maximum "write_same" length of the array. * INCIDENT NO:3427500 TRACKING ID:3376725 SYMPTOM: EMC VNX and VPLEX devices managed by PP are not shown properly in the vxdisk list output: -bash-3.2# vxdisk list DEVICE TYPE DISK GROUP STATUS emc_clariion1_146 auto:cdsdisk - - online emc_clariion1_147 auto:cdsdisk - - online emc_clariion1_148 auto:cdsdisk - - online DESCRIPTION: Output of PP CLI "powermt display options" changed adding separate entries for VNX and VPLEX classes. Therefore old logic in the PowerPath Array Support Library(ASL) to claim devices under these classes is failing, as it was written based on the old CLI output. RESOLUTION: Code changes are made to add new parsing logic for claiming EMC VNX and VPLEX devices. Correct vxdisk list output after the fix will look like: -bash-3.2# vxdisk list DEVICE TYPE DISK GROUP STATUS emcpower5s2 auto:cdsdisk - - online emcpower6s2 auto:cdsdisk - - online emcpower7s2 auto:cdsdisk - - online INCIDENTS FROM OLD PATCHES: --------------------------- NONE
