Software Distributor Requirements, Issues Fixed, and Workarounds HP-UX 11i v2, HP-UX 11i v3 (5900-2562, March 2013)

1. From the EFI shell: Manually issue the EFI shell command reconnect —r, before
attempting to boot from the alternate path.
2. Online: Use the HP-UX setboot command to swap the primary and alternate boot
devices.
3. Hardware configuration: Reconfigure by moving the alternate boot device to a different
HBA.
• Using ioscan with krm Not Running
When ioscan is run with the —fn or —Fn option, and the kernel resource monitor (krm) is
not running, there could be stale krm device files in the system, which would correspond to
different devices, including fcd, in ioscan output. This issue has no impact on the functionality
of the Fibre Channel port; however, ioscan output may be confusing. This issue can impact
any card accessible with ioscan, and is not specific to the cards supported by the fcd driver.
Corrective Action:The ioscan output can be returned to normal by either deleting the stale
krm device files, or by starting krm, which will recreate the device files.
• Increased Boot Time with Unconnected fcd HBA Ports
System boot time will be increased if there are unconnected fcd HBA ports (i.e., HBA ports
controlled by the fcd driver).
This happens because an ioscan is performed as a part of the boot process for HP-UX .
When an ioscan is performed for the first time for an fcd HBA port, the fcd driver waits for
21 seconds before declaring the port offline.
This is only an issue during boot, because at boot time the HBA ports are scanned sequentially.
After boot, the HBA ports are scanned in parallel, using kernel threads.
The delay observed during boot will be around N*21 seconds, where N is the number of
unconnected fcd HBA ports.
Corrective Action:Two workarounds are available for this issue:
1. Attach loop back hoods to all of the unconnected HBA ports. The loop back hoods will
cause the unconnected HBA ports to come online in a private loop topology.
2. Install the product bundle, mtIOScan, that enables boot time kernel threads. This will
reduce the overall boot delay due to unconnected ports to 21 seconds. This product can
be obtained from www.software.hp.com
• swlist Does Not Indicate the Mezzanine HBAs
swlist does not indicate the Mezzanine HBAs, and cannot be added onto because of string
size limitation.
Corrective Action:Refer to Hardware Requirements later in this document for more information.
• swverify reports inaccurate signature verification results if /tmp does not have enough free
space
When a digitally signed software in a depot is verified using swverify or a tape depot is
verified using swsign –v, the command may report inaccurate results if there is not enough
free space in /tmp.
Corrective Action: Ensure that there is more than 300 MB of free space in/tmp. A depot larger
than 10 GB may require more free space. Run the swjob command printed at the end of
swverify session and make sure there are no errors.
