Possible VxVM (v1.3) related operating system hang
Running VxVM (version 1.3) as the volume manager on
machines running under extreme memory pressure (such as very
low memory or heavily loaded machines) may cause the
operating system to hang. To avoid this issue:
• Increase the system memory.
• Tune the system to avoid heavy loads and extreme memory
pressure.
• Use LVM instead of VxVM as a volume manager.
Limited support for ServiceGuard
ServiceGuard is supported only on rx2600 and rx5670 systems.
PCI Bus Error Message on system boot
On the rx4610 with BIOS version 109, when you have a large
number of disks configured and/or the serial console is
configured, then it may cause the system not to boot. The system
does not see any of its internal disks and will not boot unless you
disconnect or power off all SCSI connections. The SCSI cards
affected are A5150A and A5159A.
