Technical data

The error message should read:
Unable to locate an unclaimed unit with that World Wide LUN ID.
• The spmgr display –d device command requires a device (c#t#d#) as an argument, but
accepts a WWLUNID as the argument and responds with missing or incorrect d a ta. Use only
device with the –d option.
• The spmgr select and spmgr restart commands occasionally respond with the following
error message:
Error: Invalid Argument
The command completes successfully. If you see this error, verify comm a nd success using the
spmgr display command.
• Notification event messages that contain fields for the adapter instance (td#),arrayWWNN,or
LUN WWLUNID sometimes report either DON’T CARE or * as the identi fier. This reporting error
has no impact on Secure Path operation, and specific failure or change parameters can be
viewed with the spmgr display command.
• Using spmgr set -p on|off WWNN, spmgr set -a on|off WWNN, or spmgr set
-b on|off WWNN without the on|off argument, or using spmgr set -f interval without
the interval argument always returns that parameter to the installation default values. Omit ting the
on|off argument returns path verification to on,auto-restoretooff, load balancing to off,
and the verification interval to 30 seconds.
Interoper
ability with Ignite-UX software
Ignite-UX
software does not support Secure Path 3.0F SP3 for the following reasons:
• When Secure Path 3.0F SP3 is installed on a system, the hardware addresses of all EVA disk LUNs
change. During the recovery process, importing LVM volume groups on the EVA array may fail.
• If the boo
t disk resides on an EVA array, the sy stem fails to boot due to an LVM configuration
failure.
• Secure Path 3.0F SP3 is not included in the installation kernel and is not part of the core H P-UX
operating system.

Secure Path 3.0F SP3 for Active-Active disk arrays provides the following features and fixes:
• Provi
des multipathing support to logical units presented from HP StorageWorks EVA4400
• Provides multipathing support to logical units presented from HP StorageWorks
EVA4100/EVA6100/EVA8100
• Provides multipathing support to logical units presented from HP StorageWorks

• Duri
ng a race condition when more than one application a ccess two different device special files
of s
ame end LUN for different types of I/O (say one using it for raw IO and other for block I/O),
and
if one of the application i ssues close on one of the device special files, it results in system
panic. This issue has been addressed in this release.
• An issue which could, under cer tain instances, when the path polling and open/close operations
go
es on simultaneously on the same logical unit causing system panic has been addressed
in this release.
