HP-UX 11i Features for Superdome Servers

The HP-UX 11i release includes several new commands and utilities for managing and configuring HP Superdome partitions and system hardware. Also, the new rad command and the ioscan command provide Superdome-specific output as described in the following sections.

These key HP-UX 11i Superdome features are discussed below. For details on all HP-UX 11i features see the HP-UX 11i Release Notes.

The following new HP-UX commands support managing and configuring Superdome partitions: parstatus, parcreate, parmodify, and parremove.
Two additional HP-UX commands support powering on/off Superdome hardware components and turning on/off their service LEDs: frupower, and fruled.
The new Partition Manager (parmgr) graphical utility also supports the same Superdome tasks that the above commands support.
The ioscan command provides Superdome-specific HP-UX hardware path output when you run it on Superdome servers.
HP-UX hardware paths on Superdome servers differ from hardware paths on other HP servers.
Also, the HP-UX hardware paths for PCI I/O slots within a Superdome I/O chassis do not always directly correlate to the PCI slot numbers.
See the following section (“HP-UX Hardware Paths on HP Superdome Systems”) for details on these HP-UX hardware path considerations.
The new rad command is supported on several HP systems, including Superdome, for displaying I/O card information and performing card addition and replacement tasks.
You can use the rad -q command to display a summary of a partition's available PCI I/O slots, cards, and other details. This output on Superdome servers differs from output on other servers.
See the following section (“rad Command Output on Superdome Servers”) for details on using rad on Superdome servers and for recommended restrictions.

HP-UX Hardware Paths on HP Superdome Systems

The HP-UX hardware path on HP Superdome systems is provided in the format described here. The ioscan HP-UX command reports the hardware path for components within the partition in which the command is issued.

Note that the ioscan command reports information only for the currently active hardware components in the local partition. It does not report details for hardware not assigned to the local partition.

The components of Superdome hardware paths are:

a/b/c/d/e.f.g

where these components are as follows

a
Is the global cell number.
b
Is a processor (10-13), memory (5), or a system bus adapter (0). Each Superdome I/O chassis has a single system bus adapter.
c
Is a local bus adapter (the LBA, one for each PCI card slot in the chassis). The LBA connects its corresponding PCI card slot with the system bus adapter.
NOTE: The LBA number is not necessarily the same as the PCI slot number. See “HP Superdome PCI I/O Slots and Hardware Paths” for important details.
d
Is the card's address on the slot's PCI bus.
Typically this is 0 (zero), although the Superdome core I/O card has multiple devices and addresses in a single card.
e
Is the function for the I/O card. Typically this is 0 (zero) for single-function cards.
f
Is the target of the I/O device, or SCSI ID.
g
Is a device-specific address such as a SCSI controller (initiator).

Refer to the ioscan(1M) manpage for details on using ioscan to list hardware path information.

HP Superdome PCI I/O Slots and Hardware Paths

You should note that on HP Superdome servers, the PCI card slots (within an HP Superdome I/O chassis) do not directly correspond to their local bus adapter (LBA) number, such as is reported by the ioscan HP-UX command.

The following table shows the correlation among HP Superdome PCI slots and the LBA number.

PCI Card Slot	LBA Number	HP-UX 11i Hardware Path
0	0	cell/0/0
1	1	cell/0/1
2	2	cell/0/2
3	3	cell/0/3
4	4	cell/0/4
5	6	cell/0/6
6	14	cell/0/14
7	12	cell/0/12
8	11	cell/0/11
9	10	cell/0/10
10	9	cell/0/9
11	8	cell/0/8

For an example, issue the ioscan -C ba command to lists the PCI slots ("Local PCI Bus Adapter") for your partition.

The order in which ioscan reports the PCI slots (LBA Number order) does not correlate to the order in which the slots physically are arranged (PCI Card Slot order).

rad Command Output on Superdome Servers

This section covers the rad command's output on Superdome servers. For complete details refer to the rad(1M) manpage.




	NOTE: When adding or replacing I/O cards use the equivalent SAM procedures, when possible, rather than using `rad`. See also the sam(1M) and rad(1M) manpages.

On HP Superdome servers, the rad command reports PCI card slot details as shown in the following example output. The rad command reports details showing the PCI slot (cabinet-bay-chassis-slot) and the corresponding HP-UX hardware path (cell/sba/lba/device).

For details on HP-UX hardware paths, refer to “HP-UX Hardware Paths on HP Superdome Systems”.
