 bootseq 
                           -T system:blade[x]

where x is the blade server bay number.
Set boot sequence for blade server Sets the boot sequence of the specified blade server. bootseq devicelist

where devicelist has one or more of the following boot devices specified, in order of preference:

  • floppy for the diskette drive (non-POWER-based blade servers only)
  • usbdisk for a USB device (not supported by all blade servers)
  • iscsi for iSCSI
  • iscsicrt for iSCSI critical
  • nw for network - PXE
  • nodev for no device
  • hd0 for hard disk drive 0
  • hd1 for hard disk drive 1
  • hd2 for hard disk drive 2
  • hd3 for hard disk drive 3
  • hd4 for hard disk drive 4
  • cd for the CD-ROM drive
  • usb for the media tray (non-POWER-based blade servers installed in BladeCenter T units only)
  • hyper for hypervisor (only for blade servers that use hypervisor virtualization)

  • legacy for the UEFI-specified legacy boot sequence (only for blade servers that support this feature)

                           -T system:blade[x]

where x is the blade server bay number.
Set boot sequence for blade server

(continued)

 

A boot sequence of up to four boot devices can be specified. If fewer than four devices are specified, the remaining items in the sequence are set to nodev.

This command can only be run by users who have one or more of the following command authorities:
  • Supervisor
  • Blade configuration
See Commands and user authority for additional information.
  
Set boot sequence for all blade servers Sets the same boot sequence for all blade servers installed in the BladeCenter unit. bootseq -all devicelist

where devicelist has one or more of the following boot devices specified, in order of preference:

  • floppy for the diskette drive (non-POWER-based blade servers only)
  • usbdisk for a USB device (not supported by all blade servers)
  • iscsi for iSCSI
  • iscsicrt for iSCSI critical
  • nw for network - PXE
  • nodev for no device
  • hd0 for hard disk drive 0
  • hd1 for hard disk drive 1
  • hd2 for hard disk drive 2
  • hd3 for hard disk drive 3
  • hd4 for hard disk drive 4
  • cd for the CD-ROM drive
  • usb for the media tray (non-POWER-based blade servers installed in BladeCenter T units only)
  • hyper for hypervisor (only for blade servers that use hypervisor virtualization)
  • uefi for unified extensible firmware interface (only for blade servers that support this feature)

  • legacy for the UEFI-specified legacy boot sequence (only for blade servers that support this feature)

A boot sequence of up to four boot devices can be specified. If fewer than four devices are specified, the remaining items in the sequence are set to nodev.

This command can only be run by users who have one or more of the following command authorities:
  • Supervisor
  • Blade configuration
See Commands and user authority for additional information.
  
Example: To set a boot sequence of diskette drive, CD-ROM drive, and hard disk drive 0 for the blade server in blade bay 3, while the blade server in blade bay 3 is set as the persistent command environment, at the system:blade[3]> prompt, type 
                  bootseq floppy cd hd0
To display the boot sequence for the blade server in blade bay 3, while the blade server in blade bay 3 is set as the persistent command environment, at the system:blade[3]> prompt, type 
                  bootseq

The following example shows the information that is returned from these two commands:

               system:blade[3]>  bootseq floppy cd hd0
OK
system:blade[3]>  bootseq
floppy
cd
hd0
nodev
system:blade[3]>
