Symptoms

My Sun SPARC Enterprise M3000 has a broken internal  146GB - 10000 RPM SAS Disk Assembly . My server had 4 x FUJITSU-MBD2147RC-3701, but Oracle Support sent me a FUJITSU-MBB2147RC-3703 as a replacement disk:

AVAILABLE DISK SELECTIONS:
      0. c0t0d0 <FUJITSU-MBD2147RC-3701 cyl 14087 alt 2 hd 24 sec 848>
         /pci@0,600000/pci@0/pci@0/scsi@0/sd@0,0
      1. c0t1d0 <FUJITSU-MBB2147RC-3703 cyl 14087 alt 2 hd 24 sec 848>
         /pci@0,600000/pci@0/pci@0/scsi@0/sd@1,0
      2. c0t2d0 <FUJITSU-MBD2147RC-3701-136.73GB>
         /pci@0,600000/pci@0/pci@0/scsi@0/sd@2,0
      3. c0t3d0 <FUJITSU-MBD2147RC-3701-136.73GB>
         /pci@0,600000/pci@0/pci@0/scsi@0/sd@3,0

 

FUJITSU-MBD2147RC-3701 disks are capable of using a 6Gbps data-transfer rate, where as the FUJITSU-MBB2147RC-3703 is only capable of a 3Gbps data-transfer rate.
This slower disk will slow down my zpool access times, I need a like for like disk replacement.
