Table 15. SAS boot errors (continued)
Code Message
W4342 Unsupported SAS Phys
have an established link
Description
This could indicate a hardware or SAS
Expansion Card firmware problem SAS
Expansion Card has four SAS Phys,
sometimes referred as ports. Phy 0
and Phy 1 only are physically
connected to SAS Connectivity
Modules in bay 3 and bay 4. As Phy 2
and Phy 3 are idle, no connections via
these Phys are expected.
Action
1. Reboot the blade.
2. Power down then remove and
reinstall the blade server in the
BladeCenter unit.
3. Remove and reinstall the SAS
Expansion Card.
4. Ensure the SAS Expansion Card
firmware and blade firmware
version are at the correct level.
5. If the error started after a SAS
Expansion Card firmware upgrade
or a blade server firmware
upgrade, consider a rollback to the
previous firmware versions. Check
with the documentation at
http://www.ibm.com/systems/
bladecenter/support/ to verify
whether rollback is possible.
6. Plug the SAS expansion card into
another blade server. If the problem
persists, the SAS Expansion Card
may need replacement.
7. Plug a different SAS expansion
card into the blade server. If the
problem persists, the blade server
system board may need
replacement.
