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

The type designator consists of the following parameters:
• The string iqn followed by a dot (.)
• A date code, in yyyy-mm format, followed by another dot (.)
• A reverse domain name
• (Optional) A string followed by a colon (:)
If you are using only ASCII characters (U+0000 to U+007F), the following characters are allowed:
• ASCII dash character (’-’ = U+002d)
• ASCII dot character (’.’ = U+002e)
• ASCII colon character (’:’ = U+003a)
• ASCII lowercase characters (’a’..’z’ = U+0061..U+007a)
• ASCII numeric characters (’0’..’9’ = U+0030..U+0039)
NOTE:
See section 3.2.6 of Request for Comments (RFC) 3720 (iSCSI) for a description of the iSCSI name
string profile. You can access RFC 3720 at ftp://ftp.rfc-editor.org/in-notes/
rfc3720.txt.
Workaround
Use the correct IQN syntax, as described in section 3.2.6 of RFC 3720:
• For Windows—In the initiator GUI, click Reset under Change in the General tab to reset the IQN
to the original name that was created when you installed the initiator.
• For Linux—Edit the InitiatorName setting in the initiatorname.iscsi file using the correct
syntax.
• For Linux and Windows—Reinstall the initiator to create a valid IQN.
iSCSI initiator LUNs disappear after changing the initiator IQN
The mpx100b maintains a database of targets, initiators, and LUNs, and the corresponding links
between them. When HP Command View EVA presents or removes a LUN from an iSCSI initiator, it
updates the mpx100b database. When a new IQN logs in to the mpx100b, it is considered a new
initiator and no LUNs are assigned to it. All LUN assignments to the old IQN are maintained.
Workaround
Using HP Command View EVA, unpresent the LUN from the old initiator IQN and present it to the
new initiator IQN. Remove the old initiator from the mpx100b database with either the mpx100b
Manager GUI or the CLI.
