HP StorageWorks 4400 Scalable NAS for File Serving cluster configuration guide (AN595-96004, September 2008)

1 Initial cluster conﬁgura tion

The HP StorageWorks 4400 Scalable NAS system is shipped with the cluster already conﬁgured.

Networks

HP Clustered File System uses a local network for its administrative trafﬁc. This network has been

conﬁgured with IP addresses in the 172.31.0.n network using VL AN #1 on the ProCurve 2824 network

switch. VLAN #1 includes the ﬁrst eight ports o n the switch. This private network must not be connected

to your networ

VLAN #2 on the ProCurve switch is intended to be uplinked to your network using po rt 24 to allow

access to the iLO2 on the cluster servers and the public side of the Command View server. These

Ethernet connections are conﬁgured to obtain IP addresses using DHCP. You will need to update their

conﬁgurations if you want to conﬁg ure them statically.

Storage

The ﬁrst 12 disks in the storage array are included in the EVA Default Disk Group. This disk group has

three mirrored 1 GB disks used as membership partitions for the cluster and six 250GB RAID5 vdisks

used for ﬁlesystems. The six ﬁ lesystem disks are conﬁgured into three volumes with two vdisks each using

1MB stripes. Each vdisk in the volume pair has one vdisk defaulting to use EVA 4400 controller A and

the other vdisk defaulting to use EVA 4 400 controller B. Striping each volume across both controllers

balances the I/O loa d for better throughput.

The remaining disks in the storage array can be used as necessary for other ﬁlesystems. For best

performance, all disks with the same size a nd performance should be part of the same disk group.

Filesystems

The initial cluster conﬁguration includes three PSFS cluster ﬁlesystems. On Linux systems, the ﬁlesystems

are mounted at /psfs001, /psfs002,and /psfs003. On Windows systems, the ﬁlesystems are

mounte

dat C:\psfs001, C:\psfs002,and C:\psfs003.

The HP CFS Management Console shows the ﬁlesystem conﬁguration:

• Right-click on a ﬁlesystem and select Properties to see the block size and other conﬁguration

options used for the ﬁlesystem.

• Click S

torage on the HP CFS Management Console toolbar to see information about each

ﬁlesy

stem, including its mount point, the volume used for the ﬁlesystem, and its capacity.

Add new ﬁlesystems

Use the following procedure to add a new ﬁlesystem to the cluster.

1. Use Command View to conﬁgure the disks to be used for the ﬁlesystem and make them visible

to HP Clustered File System.

2. Open the HP CFS Management Console, which can be used for the following steps.

3. Import the disks into the cluster. This step allows the cluster to control access to the disks. See

“Conﬁgure the SAN” in the HP Clustered File System administration guide.

4. Create a dynamic volume. Dynamic volumes allow large PSFS ﬁlesystems to span multiple disks or

LUNs. See “Conﬁgure Dynamic Volumes” in the HP Clustered File System administration guide.
