When to Use This Chapter
Use this chapter to monitor M8xxx Fibre Channel and serial attached SCSI (SAS) drives, and to
recover from common disk problems.
Overview of Disk Drives
The NonStop BladeSystems support these types of disk drives:
• “M8xxx Fibre Channel Disk Drives”
• “Enterprise Storage System (ESS) Disks”
• “Serial Attached SCSI (SAS) Disks and Solid State Drives” (page 142)
Most NonStop NS-series systems support the types of disk drives listed below. See the planning
guide for your NonStop system to determine the types of disk drives it supports.
• “Internal SCSI Disk Drives”
