Planning and Preparation

SAM will, generally, prevent you from performing OLAR procedures that would adversely affect other areas of the server. Refer to Conﬁguring HP-UX For Peripherals, HP Part Number B2355-90698 for detailed information.

Critical Resources Because power to the slot must be off when the old card is removed and the new card is inserted, the effects of shutting down the card’s functions must be carefully considered.

This is particularly important if there is no on-line failover or backup card to pick up those functions. For example:

•Which mass storage devices will be temporarily disconnected when the card is shut down?

•Will a critical networking connection be lost?

A critical resource is one that would cause a system crash or prevent the operation from successfully completing if the resource were temporarily suspended or disconnected. For example, if the SCSI adapter to be replaced connects to the unmirrored root disk or swap space, the system will crash when the card is shut down.

During an OLAR procedure, it is essential to check the targeted card for critical resources, as well as the effects of existing disk mirrors and other situations where a card’s functions can be taken over by another card that will not be affected.

Fortunately SAM performs a thorough critical resource analysis automatically, and presents options to you based on its ﬁndings. If you determine that critical resources will be affected by the procedure, you should replace the card when the server is off-line.

If you must take action immediately, you can use rad to attempt an on-line addition of a backup card and deletion of the target card.

Card Compatibility

On-Line Addition (OLA). When on-line adding an interface card, the ﬁrst issue that must be resolved is whether the new card is compatible with the system. Each PCI slot provides a set amount of power. The replacement card cannot require more power than is available.

The card must also operate at the slot’s bus frequency. A PCI card must run at any frequency lower than its maximum capability; however, a
