Partitioning for the AlphaServer GS80/160/320   



Each hard partition requires the following:

The following sections describe three hard partition configuration examples:

For more information about the partitioning procedures described in this section, see the AlphaServer GS80/160/320 Firmware Reference Manual.

Hard Partition Configuration Example 1  

The example configuration in Configuration Example 1 uses four QBBs to configure four hard partitions. Each hard partition contains one QBB.  

Figure 5  Configuration Example 1  
tbs

To configure an AlphaServer GS160 system with four hard partitions, enter the following sequence of SCM commands.

From the SCM console, enter the following settings for the hp NVRAM variables. Note that the values are bit masks.

SCM_E0> power off -all
 
SCM_E0> set hp_count 4
SCM_E0> set hp_qbb_mask0 1
SCM_E0> set hp_qbb_mask1 2
SCM_E0> set hp_qbb_mask2 4
SCM_E0> set hp_qbb_mask3 8
SCM_E0> set hp_qbb_mask4 0
SCM_E0> set hp_qbb_mask5 0
SCM_E0> set hp_qbb_mask6 0
SCM_E0> set hp_qbb_mask7 0
 
SCM_E0> power on -all
You can also power on or off individual hard partitions. For example, using this configuration, enter:
SCM_E0> power off -all
SCM_E0> set hp_count 4
SCM_E0> set hp_qbb_mask0 1
SCM_E0> set hp_qbb_mask1 2
SCM_E0> set hp_qbb_mask2 4
SCM_E0> set hp_qbb_mask3 8
SCM_E0> set hp_qbb_mask4 0
SCM_E0> set hp_qbb_mask5 0
SCM_E0> set hp_qbb_mask6 0
SCM_E0> set hp_qbb_mask7 0
SCM_E0> power on -partition 0
SCM_E0> power on -partition 1
SCM_E0> power on -partition 2
SCM_E0> power on -partition 3
During the powering up phases of each hard partition, status information is displayed showing how the partitions are coming on line. Pay close attention to this information and confirm that there are no failures during this process.

As each hard partition comes on line, you can start working with that hard partition's console device. Also note, that depending on the setting of the NVRAM variable AUTO_QUIT_SCM, each hard partition's console comes on line in either the SCM or SRM console mode.

From each hard partition's console, enter into the SRM console and configure any console variables specific to that hard partition. After that, boot OpenVMS in each hard partition according to standard OpenVMS procedures. For example:

The typical hard partition 0 SRM console settings for OpenVMS are:

P00>>>show bootdef_dev
bootdef_dev             dkb0.0.0.3.0
P00>>>show boot_osflags
boot_osflags            0,0
P00>>>show os_type
os_type                 OpenVMS
The typical hard partition 1 SRM console settings for OpenVMS are:
P00>>>show bootdef_dev
bootdef_dev             dkb0.0.0.3.0
P00>>>show boot_osflags
boot_osflags            1,0
P00>>>show os_type
os_type                 OpenVMS
The typical hard partition 2 SRM console settings for OpenVMS are:
P00>>>show bootdef_dev
bootdef_dev             dkb0.0.0.3.0
P00>>>show boot_osflags
boot_osflags            2,1
P00>>>show os_type
os_type                 OpenVMS
The typical hard partition 3 SRM console settings for Tru64 UNIX are:
P00>>>show bootdef_dev
bootdef_dev             dka0.0.0.1.16
P00>>>show boot_osflags
boot_osflags            A
P00>>>show os_type
os_type                 UNIX

Hard Partition Configuration Example 2  

The example configuration in Configuration Example 2 uses four QBBs to configure two hard partitions. Each hard partition contains two QBBs.  

Figure 6  Configuration Example 2  
tbs

To configure an AlphaServer GS160 with two hard partitions, perform the following sequence of SCM commands.

From the SCM console, enter the following settings for the hp NVRAM variables:

SCM_E0> power off -all
 
SCM_E0> set hp_count 2
SCM_E0> set hp_qbb_mask0 3
SCM_E0> set hp_qbb_mask1 c
SCM_E0> set hp_qbb_mask2 0
SCM_E0> set hp_qbb_mask3 0
SCM_E0> set hp_qbb_mask4 0
SCM_E0> set hp_qbb_mask5 0
SCM_E0> set hp_qbb_mask6 0
SCM_E0> set hp_qbb_mask7 0
 
SCM_E0> power on -all
As each hard partition comes on line, you can start working with that hard partition's console device.

From each hard partition's console, you enter, as in configuration example 1, into the SRM console, and configure any console variables specific to that hard partition, and then boot OpenVMS in each hard partition.

Hard Partition Configuration Example 3  

As in configuration example 2, the configuration in Configuration Example 3 uses four QBBs to configure two hard partitions; the only difference is the changing of the number of QBBs per hard partition.  

Figure 7  Configuration Example 3  
tbs

To configure an AlphaServer GS160 system, perform the following sequence of SCM commands.

From the SCM console, enter the following settings for the hp NVRAM variables:

SCM_E0> power off -all
 
SCM_E0> set hp_count 2
SCM_E0> set hp_qbb_mask0 7
SCM_E0> set hp_qbb_mask1 8
SCM_E0> set hp_qbb_mask2 0
SCM_E0> set hp_qbb_mask3 0
SCM_E0> set hp_qbb_mask4 0
SCM_E0> set hp_qbb_mask5 0
SCM_E0> set hp_qbb_mask6 0
SCM_E0> set hp_qbb_mask7 0
 
SCM_E0> power on -all
As in the other examples, as each hard partition comes on line, you can start working with that hard partition's console device.

From each hard partition's console, you enter, as in configuration example 1, into the SRM console, and configure any console variables specific to that hard partition, and then boot OpenVMS in each hard partition.

Updating Console Firmware on AlphaServer GS80/160/320 Systems  

To update the SRM console firmware on a system that is hard partitioned, you must do so separately for each hard partition. There is no way to update all of the firmware on each partition at one time.
