Known limitations and considerations
There are several considerations to be aware of when working with an HP-UX host for iSCSI.
- The HP-UX iSCSI initiator skips any IPv6 addresses and continues connections with the IPv4 addresses received during the discovery process.
- The HP-UX iSCSI initiator tries to log in on all the target IP addresses that have been found in the discovery phase. In this situation, the Storwize® V3700 system iSCSI login toggles.
- For HP-UX Fibre Channel host attachments, use the hpux host type when creating the host object. However, for iSCSI HP-UX host attachment, use the default host type when creating the host object.
- The HP-UX host does not discover the newly exported LUNs if the IBM® device files have been removed by using the rmsf command and if the deleted target IP has been re-added using the iscsiutil -a -I command. In this situation, you must reboot your HP-UX host and then add the target IP and discover the LUNs.
- The HP-UX iSCSI initiator does not log off completely even after deleting the target IP using iscsiutil -d -I command. The LUNs remain visible on the HP-UX host. If this occurs, restart the system.
