Symptoms

This document describes the extra actions you need to take when upgrading or replacing a hsPCI I/O board to a hsPCI+ I/O board: if your bootdisk is attached to slot1, aka C5V0, top right IO-slot, your domain will fail to boot.

Changes

Cause

The devicepath to the bootdisk changed as a result of the hardware upgrade.

Solution

Although the hardware seems to be transparent a reboot -r is necessary to finish the upgrade successfully and rebuild the devicetree accordingly.

If indeed the devicepath to your bootdisk is affected by the upgrade, follow the steps in Document 1008598.1 - How to rebuild the path_to_inst file and /dev/dsk and /devices directories.

Example

After replacing the HSPCI IO-board with a HSPCI+ IO-board we poweron our domain by running setkeyswitch on. After successfully going through post the domain starts booting....

..and fails because all devices in slot1 now have a different devicepath.

Our boot-device points to /pci@15c,700000/pci@1/scsi@2/disk@1,0:a.

The new HSPCI+ IO-board has an extra PCI bridge-chip, which shows at lines a/b.

Now, that we can fix.

{82} ok show-disks

a) /pci@15c,700000/pci@1/pci@1/scsi@2,1/disk

b) /pci@15c,700000/pci@1/pci@1/scsi@2/disk

q) NO SELECTION

Enter Selection, q to quit: b

/pci@15c,700000/pci@1/pci@1/scsi@2/disk has been selected.

Type ^Y ( Control-Y ) to insert it in the command line.

e.g. ok nvalias mydev ^Y

for creating devalias mydev for /pci@15c,700000/pci@1/pci@1/scsi@2/disk

{82} ok printenv boot-device

boot-device = /pci@15c,700000/pci@1/scsi@2/disk@1,0:a

{82} ok setenv boot-device /pci@15c,700000/pci@1/pci@1/scsi@2/disk@1,0:a

Now rebuild your device tree following Document 1008598.1

Note that the path to the "golden eri" is different when using an HsPCI board vs an HsPCI+ board.

Ex for HsPCI in slot 9 - SMS 1.6 / OpenBoot 4.21.0 :

{122} ok {122} ok show-nets

a) /pci@13c,700000/network@3,1

...

Ex for HsPCI+ in slot 14 - SMS 1.6 / OpenBoot 4.21.0 :

{180} ok show-nets

...

c) /pci@1dc,700000/pci@1/network@3,1

...

This path to the "golden eri" is used to create the OBP alias "man-net".

Booting on man-net still works even if the alias is not valid.

Internal Section

See Bug 6446922 man-net on HsPCI+ based 15k domain is not valid
