CS1000 Compact Flash (RMD) issue on CPPIV Processors
Background:
Issues have been observed on CS1000M single group, multi-group or CS1000E systems with CPPIV processors, in which problems with communication between the CPPIV processor and a FMD or RMD Compact Flash card can cause the system TTY to lockup, disk cache errors, an inability to access PDT, FMDs to go out of service, lose synchronization and may cause the system to go into split mode, do a graceful switchover or INI. This has been seen on a small number of 6.0 and 5.5 systems. This issue is believed not to be applicable to CS1000E systems with CPPM processors.
Analysis:
The ongoing investigation has shown that the system is most prone to these potential conditions when an RMD has just been inserted or a backup is being performed to a newly inserted RMD.
Recommendations:
The investigation is ongoing, however at this time we can provide the following recommendations:
1. Install preventative patch MPLR30442 (CPPIV only). This patch adds additional logic code to ensure that when an RMD is inserted or removed that the ATA BUS is properly reset and that the device is properly mounted and un-mounted without causing the FMD of the CPPIV to go out of service.
2. Install preventative patch MPLR30371. This patch will run a CHECKDISK on the card before doing a backup to it - if bad blocks are found the backup won't occur, thus reducing the likelihood of the problem being encountered and an INI occurring.
3. Install preventative patch MPLR28935 for release 6.0 systems only. This patch addresses a
situation in which the system will spend too much time writing to the FMD when not properly logged into a security domain. This additional time spent by the writing task can cause the system to slow down and/or INI. (Please Note that this patch has Special Instructions, including a manual INI)
4. Install preventative patch MPLR30410. This patch will optimize data block usage in the FMD.
5. Make sure that RMD cards are not inserted if MPLR30442 is not installed. If the system does not currently have the RMD inserted, modify the backup rules to backup the data using FTP. If the RMD is already inserted into the CPU and no issues are being seen on the system, run a CHECKDISK on the
SWITCHED & IPT TECHNICAL SPECIALIST CENTRES
RMD. If the CHECKDISK passes (see below for an example of a passed CHECKDISK),
then the RMD can be left in the faceplate of the CPU and continue to be used for backup purposes.
