HP A5158A Fibre Channel Adapter Release Notes

Known Problems and Workarounds (11i)

1. Problem: During online replacement (OLR) of the A5158A adapter on Superdome

systems, the replacement could fail if the adapter is connected to hub/switch/device. The

following error message will display:

OLARD error: General error

The slot will become inaccessible until you power cycle the system.

Workaround or Fix: This problem can be avoided by disconnecting the cable from the

adapter before doing OLAR operations.

2. Problem: During online replacement (OLR) of the A5158A adapter on L3000 systems, the

replacement could cause a system panic (HPMC) if the adapter is connected to

hub/switch/device. Subsequent boot will hang unless you power cycle the system.

Workaround or Fix: This problem can be avoided by disconnecting the cable from the

adapter before doing OLAR operations.

3. Problem: During online replacement (OLR) of the A5158A adapter on the L2000 system,

the replacement may fail and display the following error message:

OLARD error: General error

Workaround or Fix: This problem is ﬁxed in PDC version 41.38.

4. This problem concerns the HP Fibre Channel SNIA HBA API.

Problem: When the HBA_OpenAdapter() API returns 0, it does not set the errno variable

appropriately under the following scenarios:

• When there is a ﬁle open error, the errno variable is not set to EACCES.

• When the adapter for open is not available, the errno variable is not set to ENXIO.

• When there is an internal error, the API does not always set the errno variable to EIO.

If the errno is not set appropriately, the user application may fail to identify the cause of

the failure.

Workaround or Fix: The user application may set the errno value to 0 immediately

before the call to HBA_OpenAdapter(). If the call returns 0, the application can verify if

there is a change in the errno value. If the errno value remains 0, the API has not set the

errno value due to any one of the above listed error scenarios. Otherwise, the errno value

set by the API may be interpreted as given in the programmer’s guide.
