HP-UX iSCSI Software Initiator B.11.11.03f Release Notes (January 2009)

Limitations
The following information is for revision B.11.11.03f of the HP-UX iSCSI Software Initiator:
• iSCSI usage of IPSec is supported on HP-UX, however, the HP-UX iSCSI Software Initiator
has not been tested with IPSec due to the lack of iSCSI targets that support IPSec.
Support of IPSec with the HP-UX iSCSI Software Initiator is dependent on the availability
of iSCSI targets that support IPSec and target vendor testing of the HP-UX iSCSI Software
Initiator with those targets.
• The HP-UX iSCSI Software Initiator does not support IPv6 addresses.
• The HP-UX iSCSI Software Initiator does not support the definition of the boot, root, primary
swap, dump, or var volumes on iSCSI physical volumes.
Known Problems and Workarounds
• Problem: Kernel Registry Service states that information will be available prior to I/O
initialization. However, kernel modules that use the Kernel Registry Service to store driver
information are not available until after I/O initialization.
Workaround: Patches PHKL_27321 and PHKL_27096 must be installed to provide early
access to the Kernel Registry Services.
• Problem: ioscan displays the device state as NO_HW when nodes that have hardware paths
beginning with 255 are scanned.
Workaround: Install patch PHKL_28209.
• Problem: The shutdown command is blocked when the iSCSI Software Initiator is installed.
During shutdown, /sbin/umountall is unable to determine the status of the file system,
because the killall script has killed the iSCSI Software Initiator daemons needed to access
devices.
Workaround: Install patch PHCO_28319. This patch will modify the killall script to
prevent it from killing the iswd, iradd, and iscsi_resolvd iSCSI Software Initiator
daemons.
• Problem: Data page fault seen with transfer of data using iSCSI Software Initiator.
Workaround: Install patch PHNE_26939 to resolve data page fault issue.
• Problem: SAM does not support iSCSI.
Workaround: Install patch PHCO_27374 to provide access to iSCSI volumes from SAM.
• Problem: If SLP is being used by iSCSI, and the SLP daemon (slpd) is terminated, the islpd
iSCSI daemon is killed.
Workaround: No patch available. If a user starts or restarts the SLP daemon (slpd), the islpd
deamon must be restarted using the command line.
• Problem: Operations (for example, ioscan, vgcreate, diskinfo, and insf), that require
a device open of an SPC-2 compliant target are delayed, due to extra retries that delay the
device open of the SPC-2 compliant target.
Workaround: Install patch PHKL_30510.
• Problem: If Event Monitoring Services (EMS) and Support Tool Manager (STM) are used
for diagnostic logging and monitoring, some new events generated by the HP-UX iSCSI
Software Initiator are not processed by the iSCSI EMS Monitor. Also, incorrect event messages
can be produced because the HP-UX iSCSI Software Initiator and the iSCSI EMS Monitor
are out of sync.
Workaround: Install patch PHSS_30888 after installing the HP-UX 11i v1 Hardware
Enablement bundle: HWE0406.
