AIX Release Notes
This problem only affects IBM AIX V5.1 and V5.2. It does not affect AIX V4.3.3,
or the actual operation of the Agent or the storage system.
PCI Hot Swapping of HBAs Not Supported
Hot swapping is defined as replacing one HBA with an identical HBA in the same
PCI slot while the system is up and running. This function is not supported on
P-series systems that support hot swapping, and will hang the server if attempted.
To replace an HBA, you must first shutdown the server.
PCI Hot Addition of HBAs Not Supported
Hot Adding is defined as adding a PCI HBA to an empty PCI slot while the
system is up and running. This function is not supported on the P-Series servers
and the hot addition of the HBA will fail. The server will have to be shutdown in
order to add an HBA.
HBA Driver Does Not Support Extended Error Handling (EEH) on P690
Extended Error Handling (EEH) is a mechanism built into the P-series servers that
allows the server to isolate a faulty HBA and shut it down. The PC1000F HBA
solution does not support IBM EEH. This means that an errant PC1000F HBA
cannot electrically be taken offline by the P690 CPU. The availability of the P690
solution with PC1000F is equal to other IBM server models.
Maximum LUN Support
This version of the HBA driver supports 32 LUNs per target. This means a
subsystem can have the theoretical maximum of 64 LUNs (including CCL units)
per RAID subsystem.
Note: This LUN limitation does not apply to Secure Path for AIX. Refer to the Secure
Path documentation for details.
