2.2 Changed Features

The following feature was introduced in RAID-01 version B.11.31.0906 with limited controller

support; it is now supported on all Smart Array controllers:

• The ciss driver creates a virtual bus interface to support up to 1024 devices or lun paths.

Version B.11.31.0906 of the ciss driver now creates a virtual bus interface to support up to

1024 devices or lun paths.

The following example shows a partial ioscan command output, with a discovered Smart

Array P700m and devices:

ext_bus

/dev/ciss5

ext_bus 2 0/4/0/0/0/0.1.1

ciss_vbus CLAIMED INTERFACE CISS Device Interface

disk 10 0/4/0/0/0/0.1.1.0.1 sdisk CLAIMED DEVICE HP MSA2312sa

/dev/dsk/c2t0d1 /dev/rdsk/c2t0d1

The hardware path

for the LUN is

changed because the

driver registers as a

virtual bus device

interface.

The virtual bus

interface appears as

ext_bus.

4 Known Problems and Limitations

This section provides a list of problems and limitations known to HP when these release notes

were published. If workarounds are available, they are included.

4.1 For All Smart Array Controllers

• Unnecessary reboot occurs when removing the ciss driver.

If you use the swremove command to remove the dynamically loaded ciss driver, the

Critical Resource Analysis (CRA) can fail. This causes swremove to incorrectly reboot the

system.
