HP-UX System Administrator's Guide: Routine Management Tasks

1. Access the EFI Shell environment using the server’s (or nPartition’s) system
console. Access the system console either via the server’s management processor
(MP) or via a hardwired console terminal.
If necessary, interrupt the autoboot process by hitting a key during the autoboot
time-out period. The EFI Boot Manager will display the boot options menu (the
EFI main menu).
From the boot options menu, select EFI Shell.
2. Select the device with the AUTO file that you want to change.
IMPORTANT: Do not forget this step, especially if you have multiple bootable
devices. On HP Integrity Servers every bootable device can have its own AUTO
file. If you have not selected the device containing the AUTO file you want to change,
you might be editing an AUTO file on a different device.
To list all currently mapped file systems, enter map at the EFI Shell prompt:
Shell> map
The map command displays all file systems that are known and have been mapped.
For example:
fs0 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)/HD(Part1,Sig88F40A3A-B992-11E1-8002-D6217B60E588)
fs1 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)/HD(Part3,Sig88F40A9E-B992-11E1-8004-D6217B60E588)
blk0 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)
blk1 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)/HD(Part1,Sig88f40A3A-B992-11E1-8002-D6217B60E588)
blk2 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Primary,Master)/HD(Part1,Sig88f40A6C-B992-11E1-8003-D6217B60E588)
blk4 : Acpi(HWP0002,500)/Pci(2|0)/Ata(Secondary,Master)
If the map command shows a lot of devices you can use the -b option to make it
show the output one screen at a time.
In the list that is displayed locate the entry corresponding to the device containing
the AUTO file you want to change. Look at the entries in the list that begin with the
string fs#, where # will be a number (for example fs0, fs1, fs2 ... and so on).
At the EFI Shell prompt enter the fs# for the desired device followed by a colon:
Shell> fs0:
Your device is now selected and the EFI Shell prompt will change to reflect that:
fs0:\>
