HP StorageWorks EVA4400 iSCSI Connectivity Option (mpx100b) 5.0 (5697-0512, June 2010)

iSNS IP address and IPv4, IPv6
When the IP address for the iSNS server is changed from an IPv4 address to an IPv6 address, or from
an IPv6 address to an IPv4 address, the command completes successfully but the change does not
take place.
Workaround
Disable iSNS for the existing address before setting the new address.
Sequence out-of-range errors—Microsoft initiator
The CmdSN out of range error messages may be logged as Critical. You can view them by issuing
a show logs command to the mpx100b. Despite the message, this is not a critical issue; it is
displayed only when using the Microsoft initiator. The commands are reissued and completed to the
target.
Incorrect function error during iSNS registration
You may see the incorrect function error during the Microsoft iSCSI initiator's initial iSNS
target discovery.
Workaround
To complete the iSNS target discovery, click the Refresh button on the Target tab in the iSCSI initiator
GUI.
OS-type change ineffective
If you attempt to change the OS type on a pair of redundant mpx100b's using the GUI or the command
line interface (CLI), HP Command View EVA may not display the change properly due to a mismatch
between the mpx pair.
Sun Solaris server does not support EVA LUN 0
By default, LUN 0 is assigned to an iSCSI initiator when the initiator logs in to the mpx100b iSCSI
target and when HP Command View EVA presents a virtual disk to an iSCSI host. Because the Solaris
iSCSI initiator does not recognize LUN 0 as the EVA controller console LUN, the initiator tries to bring
LUN 0 online, resulting in the following warning:
Mar 21 08:04:09 hdxs8j: [ID 248668 kern.warning] WARNING:
iscsi driver unable to online iqn.1986–03.com.hp:fcgw.mpx100b:hdxh05–
m2.0.50001fe1500aef60.50001fe1500aef68 LUN 0
To prevent LUN 0 from being sent to the Solaris iSCSI initiator, disable the Controller Lun
AutoMap parameter with the mpx100b system settings. This also prevents LUN 0 from being presented
to any host entry in HP Command View EVA 8.0 with any iSCSI host mode setting of Solaris.
LUN 0 is the HSV controller device. By default, the HSV is not included in the /kernel/drv/
scsi_vhci.conf file and is treated as an asymmetrical device for LUN access.
