Dell PERC6 firmware maintenance release version 6.2.0-0013 Performance enhancements include significant improvements in random-write performance, multi-threaded write performance, and reduction in maximum and average I/O response times.

1. When viewing SATA physical disk properties from Ctrl-R or other management applications, the Vendor Identification will be translated as "ATA" followed by blanks. 2. If all physical disks making up a virtual disk are removed from the system or enclosure, the RAID controller will delete the virtual disk. If the disks are later re-inserted, they will be marked foreign and can be imported using a management application. 3. If a virtual disk is configured with write-back cache enabled and some or all of its physical disks are removed from the system or enclosure, the RAID controller will preserve the virtual disk's write cache. The controller will flush the preserved cache when the physical disks are replaced and the foreign configuration is imported. Any attempt to update controller firmware will be blocked when cache is preserved for a virtual disk. 4. Physical disks determined to contain a foreign configuration are not available for configuration as a new dedicated or global hot spare, or as a member of a new virtual disk. The foreign configuration must be imported or cleared from the physical disk before it may be used as a hot spare or member of a virtual disk. Physical disks with a foreign configuration will not appear on the Create New VD screen in Ctrl-R. 5. Prior to performing a virtual disk migration to another system, the source system must be powered off before removal of the physical disks to preserve the correct virtual disk state. This is not required for the target system and the physical disks may be inserted while the system is powered on or off. 6. The controller restricts the importing of virtual disks that are undergoing RAID Level Migration or Capacity Expansion. Do not interrupt virtual disks that are performing either of these operations because it will disable the ability to import the virtual disk and the data will be unavailable. Dell recommends that the user perform a data backup before starting these operations. 7. EMM changes or drive migrations are not supported during a Capacity Expansion or Raid Level Migration. This may cause the VDs to go offline. Dell recommends the user to perform a data backup before starting these operations. 8. This version of firmware will not ensure complete compatibility with an older version of management applications. OpenManage 5.5 or greater is recommended. 9. It is recommended that the customer upgrade the management application and device driver to the latest version available from Dell at the time of installation of this firmware. 10. Important Information for Update Packages for Microsoft Windows a. Do not run other applications while executing Dell Update Packages. b. Do not run storage controller update packages if the controller is in use by other applications. The firmware upgrade may fail if any of the RAID controllers in the system are performing I/O background tasks (consistency checks, background initializations, rebuilds, or reconstructions). Allow the background tasks to complete before attempting to upgrade the firmware. Patrol Read tasks will not affect firmware upgrades. 11. Important Information for Update Packages for Linux a. Do not run other applications while executing Dell Update Packages. b. If the following error occurs, "Error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory", you must install the compatibility libraries. These libraries can be found on the installation media or online. To install the compatibility libraries, use the following commands: "rpm -ih compat-libstdc++-33-3.2.3.-*.i386.rpm" for RHEL 4 or 5 "rpm -ih compat-libstdc++-5.0.7-*.x86_64.rpm" for SLES 10 c. When Update Packages stop abruptly due to a power outage or abnormal termination, perform the following steps: - Remove the lock file. - Type the following command: rm -f /var/lock/.spsetup - Run the Update Package again to reapply the update. d. Do not ru

1. Enhanced disk IO performance in multiple SAS and SATA configurations. 2. Improved random IO performance. 3. Improved response and completion times for random IO. 4. Increased SATA disk command queue depth. 5. Improved disk medium error correction in certain scenarios. 6. Improved handling of faulty backplanes and enclosures. 7. Resolved an issue where a predicted failure was still being reported after that drive was replaced. 8. Corrected an issue where SATA disks in an MD1000 may become foreign after the server and enclosure are power-cycled. 9. Resolved an issue where the controller could not handle a large number of rebuilds under heavy IO stress. 10. Fixed an issue where Windows Server 2008 installation in uEFI mode fails when installing to a virtual disk larger than 2 terabytes. 11. Fixed an issue where some Intel platforms with a PERC 6 installed occasionally fail with Windows Hardware Malfunction blue screen error during OS reboots. 12. Made several cosmetic and usability enhancements to improved customer experience.
