Overview

The Enterprise 250 server can accommodate up to six internal UltraSCSI disk drives. Each drive is labeled with a disk slot number between 0 and 5.

In order to perform a disk hot-plug procedure, you must know the slot number of the faulty disk (0 through 5) and its logical device name (for example, c0t11d0). If you know the disk slot number, it is possible to determine the logical device name, and vice versa. It is also possible to determine both the disk slot number and the logical device name if you know the physical device name (such as /devices/pci@1f,4000/scsi@3/sd@b,0). Physical device names are typically provided in SCSI error messages generated by software.

This chapter provides procedures for:

• "Mapping From Error Message to Disk Slot Number and UNIX Logical Name"

• "Mapping From UNIX Logical Name to Disk Slot Number"

• "Mapping From Disk Slot Number to UNIX Logical Name"

If you use Solstice(TM) SyMON(TM) software to monitor your Enterprise 250 server, there is no need to perform the following procedures. Solstice SyMON displays disk slot numbers together with physical and logical device names in its Physical View and Logical View consoles. For additional details, please see the Solstice SyMON User's Guide supplied with your version of Solstice SyMON.
