Figure 10-9 Edit Topology - Add Host Port
If the port WWN is already visible to the storage server, you can select the WWN from the
dropdown . If it is not listed, enter the port WWN manually in this field. To rescan for new
HBAs, click Refresh.
Select the hosts operating system from the “Host Type” drop down, and also enter a unique
name for the new host port in the “HBA host port alias” field. Click Add and the new host port
will be added to your host.
Replace HBA
Remember, storage partition assignments are based on WWN ports - the DS3000 only
communicates through the WWNs (8.1.1, “What is a host?” on page 136). If you have to
replace an HBA, the adapter WWN will change. Since the new WWN does not appear in any
of the storage partition assignments, after replacement, this host port will have no access to
any logical drives. To re-enable the new WWN’s access to the assigned logical drive, you
have to tell the DS3000 about the new HBA.
After you have replaced the HBA and connected the cable, highlight the old HBA host port in
the Host topology view. Click the Replace HBA Button, and the “Replace HBA Host Port”
window appears (Figure 10-10). If the storage subsystem already sees the new HBA you will
be able to select the WWN in the “New HBA host port world wide identifier” drop down,
otherwise type the new WWN manually in this field. If you want to edit the HBA host port alias
you can also do this here. Click OK to save the settings to the storage subsystem. Now the
host will be able to access its logical drives again over the new host port.
