Summary of Change

What’s New for Customers Migrating from HP-UX 11i v1 September 2005?

PCI Card Online Deletion (OLD) is new for customers migrating to HP-UX 11i v3. It was not previously delivered on the HP-UX 11i v1 September 2005 release.

What’s New for Customers Migrating from HP-UX 11i v2 June 2006?

For HP-UX 11i v3, the PCI OL* feature has been enhanced to include online deletion of PCI cards and associated drivers. For HP-UX 11i v2, the OL* feature provided online addition and replacement of PCI cards.

Impact

The OLD feature will allow customers to delete PCI cards and associated drivers from a running system without requiring a system reboot.




	IMPORTANT: If a system is booted, or an Online Addition operation is completed, with the latch on a PCI slot in the open position, the slot may become unusable, requiring a boot to return the slot to a usable state. The 3 scenarios where this may happen are: Booting with the latch of an occupied PCI slot in the open position results in the card in that slot being unusable. The ioscan command will show the software state for the card in that slot as `UNUSABLE`. Also, a `PCIError Reported at <H/W path>` message will appear on the console. Booting with the latch of an unoccupied slot in the open position, then adding a card to that slot and executing an ioscan command, will result in the card being in the `UNSUSABLE` state (provided the `-k` option is not used and the ioscan is not restricted from covering the path to that slot). In this scenario, the card will become `UNUSABLE`, regardless of whether the latch is closed or left open, after the card is added to the slot. Performing a PCI card online addition (OLA) operation using the olrad command or the pdweb GUI, and leaving the latch of the slot opened while bringing the card online, results in the card being in the `UNUSABLE` state. This behavior is due to a firmware issue. Until a firmware fix is available, you can use the following procedure to recover: Close the latch on the PCI slot that is in the `UNUSABLE` state. Reboot the system; the slot will become usable again. Scope: This problem occurs under the following conditions: Operating System: HP-UX 11i v3 HP 9000 servers: rp8420 or rp7420 Firmware Version: PDC firmware version: 24.1 Note: To verify the PDC firmware version, you can run STM, or you can run the sysrev command from the management processor Command Menu (CM) prompt as follows: `MP:CM> sysrev`
