Unexpected LED Behavior
An unexpected LED behavior occurs when you create a RAID volume using internal drives.
All of the LEDs on the disks in the volume blink at the same time about every 16 seconds.
This behavior is normal and can be ignored.
Onboard Ethernet Port
The onboard Ethernet port of the SPARC Enterprise T5140/T5240 does not support half
duplex transfer at any of the speeds of 10M/100M/1000M.
Therefore, connect it to a switch/hub that supports full duplex transfer.
False Intermittent SATA Errors Seen on SPARC
Enterprise T5140 and T5240 Servers (CR 6880299)
When booting some systems with SATA DVD devices intermittently log port failure errors in
/var/adm/messages. The following shows an example of typical error messages:
/pci@400/pci@0/pci@1/pci@0/usb@0,1 (ohci1): Connecting device on port 1 failed
/pci@400/pci@0/pci@1/pci@0/usb@0,2 (ehci0): Connecting device on port 2 failed
Workaround: You can ignore these messages.
