Configuring an EMC Boot Device
Trespassing the Boot LUN Using atf_trespass
Follow these steps to use the atf_trespass command to trespass the boot LUN:
1.Boot the host and log in to Windows.
2.Windows NT 4.0 will have the boot LUN configured for ID 0 as described under Preparing the Storage System on page
For Windows 2000, follow these steps to determine the LUN ID of the boot LUN as seen by the host:
a.From the Windows task bar, select Start, Programs, Administrative Tools, Computer Management.
b.On the Computer Management window, click Disk Management.
c.Locate the System disk in the list. This is typically Drive C:\ and will be noted with (System).
d.Select the Disk X description area, and from the Action menu, select Properties.
A display appears with a line similar to the following:
Device Type: SCSI (Port: 3, Target ID: 1, LUN:0)
e.Find this Device Type line and note the LUN value. In this example, the LUN value is 0. This is the Host LUN ID you will need in the next step.
3.Open a command window and direct the multipath and failover software to trespass the LUN. If you are using ATF, open a command prompt and change to the multipath and failover software directory; then enter the atf_trespass command:
•If the boot LUN is owned by SP A, enter commands in the following form to transfer it to SP B:
cd Program Files\emc\atf atf_trespass atf_sp0 1:1:n
where n is the Host LUN ID you discovered in step 2.
•If the boot LUN is owned by SP B, enter commands in the following form to transfer it to SP A:
cd Program Files\emc\atf atf_trespass atf_sp0 0:1:n
These commands transfer the boot LUN to the other SP so you can configure it for failover in the HBA BIOS.
