Known Problems and Workarounds

Initiator will return the errno “ENETUNREACH” (Network is unreachable), when iSCSI devices are accessed
prior to the completion of network initialization. Once the network subsystem is initialized, the iSCSI
Software Initiator will no longer return the errno “ENETUNREACH”. Any errno that is returned after
network initialization will be the same as if the iSCSI Software Initiator were not installed on the system.
Workaround: Install patches PHKL_32854 and PHCO_29379.
• Problem: For HFS file systems residing on LVM Logical Volumes that are defined on iSCSI Physical
Volumes, fsclean retries the open for the PV to become available, on 10 second intervals, for a total of
360 seconds. This will prolong the system startup time, depending on the number of HFS file systems
configured.
Workaround: Install patches PHKL_32854 and PHCO_29379.
• Problem: File system commands executed against iSCSI devices display error messages.
During system startup, file system commands (such as fsck, fsclean and mountall) executed against
iSCSI raw devices, or LVM Logical Volumes that are defined on iSCSI Physical Volumes, will generate
error messages, because iSCSI devices will be inaccessible prior to network initialization.
Workaround: Install the following patches:
PHCO_33203 makes fsclean(1m) iSCSI aware.
PHCO_33205 makes mountall(1m) iSCSI aware, and perform required actions while trying to
mount/fsck iSCSI devices.
PHCO_33221 makes HFS bcheckrc aware of fsck(1m)'s error code for iSCSI devices.
PHCO_33226 makes VxFS bcheckrc aware of fsck(1m)'s error code for iSCSI devices.
PHCO_33236 makes VxFS mount(1m) iSCSI aware
PHCO_33237 makes VxFS fsck(1m) iSCSI aware.
PHCO_33242 makes HFS fsck(1m) iSCSI aware.
PHCO_33327 makes mount(1m) iSCSI aware.
• Problem: The Veritas Volume Manager (VxVM) support with the iSCSI Software Initiator requires the
VxVM patch.
Workaround: Install VxVM patch PHCO_30850.
Known Problems and Workarounds for the HP-UX iSCSI Software Initiator
Revision B.11.23.03e
• Problem: For HFS file systems residing on LVM Logical Volumes that are defined on iSCSI Physical
Volumes, fsclean retries the open for the PV to become available, on 10 second intervals, for a total of 360
seconds. This will prolong the system startup time, depending on the number of HFS file systems
configured.
Workaround: Install patch PHKL_32855.
• Problem: During system start-up, the VxFS file systems residing on iSCSI devices cannot be fsck'ed
causing the bcheckrc to drop the control into a shell. This needs manual intervention to continue with the
boot. This defect exists on HP-UX 11i v2 with JFS 3.5 only.
Workaround: Install patch PHCO_32912
