Installation and configuration notes
The following list contains the notes and the known issues that relate to the installation and configuration of the appliance:
When you attempt to copy a software update to the share directory, do not initiate any other commands until the copy finishes. If you run a command during the copy process, you may see that the software update is listed and available. However, if you install that software update, it can fail.
iSCSI supports IPv4 addresses only. iSCSI connections over IPv6 are not supported. In addition, the initiator and the target must be on the same Layer 2 network (L2).
Only a QLogic Small Form-Factor Pluggable (SFP+) module is supported in the 10Gb Ethernet/iSCSI card. This requirement applies to configuration H of the NetBackup 5240 appliance. Configurations A, B, C, D, and E of the NetBackup 5340 appliance also support iSCSI.
A VLAN can be configured on either the network interface or the iSCSI interface. If a VLAN is configured on both the network and iSCSI interfaces, the VLAN for the network interface is effective on both the interfaces. Note that when VLAN is configured on both the network and iSCSI interface on different subnets, the configuration is not supported.

When targets are discovered by using iSNS on two iSCSI interfaces, only the recent record is displayed by the Target Show All command. For example if you run the Target Discover iSNS command for iscsi1 and then iscsi2, the column in the Target Show All command output may not show both of the interfaces (iscsi1, iscsi2) for some targets. It actually shows the interface from the most recent command (iscsi2 in this case) for some targets.
The iSCSI> Target Disconnect command takes more time to complete if workloads are running on the iSCSI interface.
You may see the following messages appear on the NetBackup Appliance Shell Menu:
Message from syslogd@host at Sep 12 10:09:14 ... iscsid: Message from syslogd@host at Sep 12 10:13:27 ... iscsid: Message from syslogd@host at Sep 12 10:17:53 ... iscsid:
These messages may appear at different times on the NetBackup Appliance Shell Menu. They may appear when you are running an iSCSI command, in the middle of a command output, or even when the console is idle. These messages are harmless and should be ignored.
When CHAP authentication is enabled on a target device and targets are discovered by using iSNS, the iSCSI > Target Discover command may not prompt for target credentials.
When you perform the role configuration during the initial configuration on an appliance with version 3.2 or later, some MSDP parameter settings are changed. However, the new settings are not enforced automatically after completing the initial configuration. To resolve this issue and enable the new MSDP parameter settings requires that you restart the NetBackup services manually.
