I.2 Method of Specification With a PHY Number
I.2 Method of Specification With a PHY Number
This method uses the PHY number corresponding to the mounting slot of a built-in disk to identify the disk used as a boot device.
You can use this specification method when specifying a standalone built-in hard disk as a boot device. However, you cannot use it to specify a built-in hardware RAID.
Table I-2 lists the PHY numbers corresponding to disk slots.
Disk Slot | PHY Number |
---|---|
Built-in disk slot #0 | 100 or 0 |
Built-in disk slot #1 | 101 or 1 |
Built-in disk slot #2 | 102 or 2 |
Built-in disk slot #3 | 103 or 3 |
Built-in disk slot #4 | 104 or 4 |
Built-in disk slot #5 | 105 or 5 |
Built-in disk slot #6 | 106 or 6 |
Built-in disk slot #7 | 107 or 7 |
To find the PHY number of the boot disk, execute the probe-scsi-all command on OpenBoot PROM, and check the PhyNum value.
{0} ok probe-scsi-all /pci@8000/pci@4/pci@0/pci@0/scsi@0 FCode Version 1.00.56, MPT Version 2.00, Firmware Version 13.00.54.00 Target a Unit 0 Disk TOSHIBA MBF2300RC 3706 585937500 Blocks, 300 GB SASDeviceName 50000393d82891d0 SASAddress 50000393d82891d2 PhyNum 0 PHY number Target b Unit 0 Disk TOSHIBA MBF2300RC 3706 585937500 Blocks, 300 GB SASDeviceName 50000393d8289180 SASAddress 50000393d8289182 PhyNum 1 Target e Unit 0 Encl Serv device FUJITSU BBEXP 0d32 SASAddress 500000e0e06d233d PhyNum 14 |
Boot Device Notation
<Device path of the SAS controller>/disk@pX,Y:Z |
Here, specify the PHY number corresponding to the mounting disk slot, for the X after "disk@p". Furthermore, specify the logical unit number (LUN) and slice number of the internal storage, for Y and Z, respectively.
Note - You can omit the logical unit number (LUN) and slice number. If omitted, LUN "0" and slice number "a" are assumed specified. If internal storage is used as the boot device, LUN "0" and slice number "a" are specified, so these numbers have the same values as when omitted. Therefore, in the use example, the notation is in a form that omits the LUN and slice number. |
Use Example
Specify the following, where "0" is the PHY number of the boot disk.
{0} ok boot /pci@8000/pci@4/pci@0/pci@0/scsi@0/disk@p0 |
