accessible; however, there are no known methods for forcing the array to start
compacting or to force a rebuild operation. If these rare circumstances occur and
result in this type of invalid array, complete the following steps:
1. Back up the data on the array.
2. Delete the array.
3. Initialize the hard disk drives that were used in the previous array.
4. Create a new array, using the same drives.
5. Format the new logical drive.
6. Restore the data.
System hang issues with ServeRAID-8i on enterprise servers
ServeRAID firmware builds 11835 to 11844 introduced performance improvements.
The new code level inadvertently exposed a weakness in early revisions of the
Complex Programmable Logic Device (CPLD) microcode in some systems
(identified in the following list). Upgrade the CPLD code on the following servers
before you apply ServeRAID firmware version 11844 or later:
v System x3800, type 8865, any model
v System x3800, type 8866, any model
v System x3850, type 8863, any model
v System x3850, type 8864, any model
v System x3950 E, type 8874, any model
v System x3950 E, type 8879, any model
v System x3950, type 8872, any model
v System x3950, type 8878, any model
v xSeries 260, type 8865, any model
v xSeries 366, type 8863, any model
v xSeries 460, type 8872, any model
v xSeries MXE-460, type 8874, any model

After upgrading firmware, the server crashes every 8-10 days
Upgrading servers that are running ServeRAID Firmware build 92xx to build 118xx
might be exposed to an issue that results in an unexpected system reset
approximately every 8-10 days.
