SUMMARY OF KNOWN ISSUES: ----------------------------------------- NONE KNOWN ISSUES : -------------- NONE FIXED INCIDENTS: ---------------- PATCH ID:6.2.1.000 * INCIDENT NO:3655872 TRACKING ID:3646712 SYMPTOM: The ASL sometimes fails to claim a path pointing to a disk as it incorrectly identifies the path as a command device. DESCRIPTION: ASL determines if a path is a command device by analyzing the appropriate bits of the SCSI page 0xC0. The SCSI page 0xC0 may or may not return the required bits of information. Thus, the ASL incorrectly assumed that the bits are invariably returned, which lead it to searching at random bits of data to determine whether the path is a command device. RESOLUTION: The ASL code is modified to verify that the correct data is returned for the SCSI page 0xC0 before ASL determines the command device. * INCIDENT NO:3714854 TRACKING ID:3697095 SYMPTOM: With root disk encapsulated or DMP Native Support set to on and if ASLAPM is installed or upgraded, the old ASL/APM files and keys are used after a reboot. DESCRIPTION: The issue is observed when the initramfs/initrd file is not recreated with the updated ASL/APM modules and keys. As a result, when the system is rebooted, the old ASL/APM files are loaded. RESOLUTION: The code is modified to incorporate new ASLAPM modules and keys. * INCIDENT NO:3727397 TRACKING ID:3736515 SYMPTOM: VxVM disk group creation may fail with SCSI-3 Persistent Reservation (PR) errors on STEC SSD DAS devices: VxVM vxdg ERROR V-5-1-585 Disk group sfcache_defaultdg: cannot create: SCSI-3 PR operation failed DESCRIPTION: This failure occurs because STEC SSD DAS devices do not support SCSI-3 Persistent Reservation (PR). RESOLUTION: The STEC Array Support Library(ASL) code is modified to mark that devices do not support SCSI-3 Persistent Reservation (PR). INCIDENTS FROM OLD PATCHES: --------------------------- NONE
