Hi,

I noticed that our new T7-1 only has one SASHBA controller but our prev. generation T4-1 servers had two. Why is that so?

root@t4-1:/ # prtdiag -v | grep SAS

/SYS/MB/SASHBA0   PCIE  scsi-pciex1000,72                 LSI,2008   5.0GT/x8   5.0GT/x8

                        /pci@400/pci@1/pci@0/pci@4/scsi@0

/SYS/MB/SASHBA1   PCIE  scsi-pciex1000,72                 LSI,2008   5.0GT/x8   5.0GT/x8

                        /pci@400/pci@2/pci@0/pci@4/scsi@0

vs.

root@t7-1:/root # prtdiag -v | grep SAS

/SYS/MB/SASHBA    PCIE  scsi-pciex1000,97                 LSI,3008   8.0GT/x8   8.0GT/x8

                        /pci@301/pci@2/scsi@0

Does that mean the internal disks are not multipathed anymore? (See "How to Identify Internal Disk Slot Numbers Using the mpathadm Utility on T3/T4 systems (

Howdy, Stranger!
