3.7.0 HP StorageWorks HP Scalable NAS File Serving Software installation guide HP Scalable NAS for Linux (AG513-96004, October 2009)

• On Brocade switches only, run the snmpMibCapSet command on the switch.
Change the famib setting to yes and accept the default values for the other
settings.
• If the servers are connected to switches in multiple fabrics, the physical ports on
each switch must be assigned to unique domain IDs. A different domain ID must
be used on each fabric (any given domain ID can exist on only one fabric in the
SAN). For example, if a server is connected to two switches that are not in the
same fabric, switch1 could use domain ID 6 and switch2 could use domain ID
7. Domain ID 6 must not exist on the fabric containing switch2 and domain ID
7 must not exist on the fabric containing switch1.
Typically these tasks can be performed from the Fibre Channel switch or from
third-party applications. Refer to your FC switch or application documentation for
more information. For EMC PowerPath, also refer to the PowerPath documentation
for zoning requirements.
2. Install a supported operating system
You will need to install a supported operating system and then modify certain system
files. See Appendix A, page 55, for more information.
3. Configure firewalls (optional)
It is important to configure firewalls appropriately. Following are some considerations:
• For RHEL5, the default OS installation configures firewall rules that prevent the
correct operation of HP Scalable NAS. HP recommends that you either select the
“No firewall rules” option, or select “Custom” and then ensure that the service
ports required by HP Scalable NAS are open.
• For SLES10, if you will be installing a firewall, ensure that the service ports re-
quired by HP Scalable NAS are open.
• If NFS or Samba/CIFS will be used, their service ports must also be open.
Following are the network ports used by HP Scalable NAS, NFS, and Samba/CIFS.
External network port numbers
The following port numbers are used for external connections to HP Scalable NAS.
If HP Scalable NAS is behind a firewall, it may be necessary to change the firewall
rules to allow traffic on these ports.
