The SPARC T5-8 server does not support some older versions of the StorageTek 8 Gb FC PCI-Express HBA that run at 5 Gbytes with a x4 channel. The SPARC T5-8 server supports cards that run at 2.5 Gbytes with a x8 channel. Note that the bandwidth and performance are the same for both types of HBAs.
If you have already installed the StorageTek 8 Gb FC PCI-Express HBA, you can check the version by using the fcinfo(1M) command. Or, if the fcinfo(1M) command does not return data about the HBA, you can use the prtconf(1M) command to check the speed and channel width of the HBA.
If the older version of the HBA is installed, the output will look like this:
# fcinfo hba-port HBA Port WWN: 21000024ff56bce8 Port Mode: Initiator Port ID: 0 OS Device Name: /dev/cfg/c28 Manufacturer: QLogic Corp. Model: 371-4325-02 ...
If the new version of the HBA is installed, the output will look like this:
# fcinfo hba-port HBA Port WWN: 21000024ff56bce8 Port Mode: Initiator Port ID: 0 OS Device Name: /dev/cfg/c28 Manufacturer: QLogic Corp. Model: 7076907 ...
If the older version is installed, and if the fcinfo(1M) command did not return data about the HBA, use the prtdiag(1M) command to obtain the data.
If the old version is installed, the output will look like this:
# prtdiag ... /SYS/RCSA/PCIE7 PCIE SUNW,qlc-pciex1077,2532 QLE2562 5.0GTx4 /pci@540/pci@1/pci@0/pci@e/SUNW,qlc@0 /SYS/RCSA/PCIE7 PCIE SUNW,qlc-pciex1077,2532 QLE2562 5.0GTx4 /pci@540/pci@1/pci@0/pci@e/SUNW,qlc@0,1 ...
If the new version is installed, the output will look like this:
# prtdiag ... /SYS/RCSA/PCIE3 PCIE SUNW,qlc-pciex1077,2532 QLE2562 2.5GTx8 /pci@340/pci@1/pci@0/pci@6/SUNW,qlc@0 /SYS/RCSA/PCIE3 PCIE SUNW,qlc-pciex1077,2532 QLE2562 2.5GTx8 /pci@340/pci@1/pci@0/pci@6/SUNW,qlc@0,1 ...
Workaround: There is no workaround for this issue. You must replace the older version with the newer version of the HBA.
