Setting Up Storage Units For Zseries Hosts Running Linux - HP XP20000/XP24000 Operation Manual

Setting up storage units for zSeries hosts running Linux

You must begin by first collecting the following software configuration information to prepare a Linux
system for accessing the storage unit through a Fibre Channel:
Host name of the server hosting the Linux system.
Device address and CHPID of the FCP port that is attached to the Linux machine. FICON/zHPF
requires a CHPID type FC.
WWPN of the FCP port on the zSeries
WWPN of the Fibre Channel port on the storage unit
Fibre Channel port on the storage unit
This information can be obtained from the HMC, the IBM TotalStorage DS Storage Manager, and
the SAN switch.
To set up the LUNs for use with your Linux system, you must first define the system to the storage unit.
You can do this through the IBM TotalStorage DS Storage Manager. The following instructions assume
that you are familiar with the IBM TotalStorage DS Storage Manager.
1. Log on to the IBM TotalStorage DS Storage Manager and select Real-time manager > Manage
hardware > Host systems.
2. From the Select Action drop-down list, select Create, then click Go.
3. From the General host information panel, complete the following fields for each Fibre Channel
host adapter:
Host type
Nickname
Description
When you are finished, click OK.
4. From the Define host ports panel, specify the host ports for this host. Click Add to add each host
port to the defined host ports table.
5. From the Define host WWPN panel, specify the worldwide port names for the selected hosts.
When finished, click Next.
6. From the Select storage images panel, specify the storage image for attachment. Click Add to
add the storage image to the selected storage images table. When finished, click Next.
7. From the Specify storage image parameters panel, specify the following parameters for each
storage image.
Host attachment identifier v Volume Group for host attachment
Type of I/O port (any valid storage image I/O port or a specific I/O port)
8. Click Apply to apply the current attachment assignment. Use this button to go through this page
for each host attachment identifier that you want to assign to the storage image. When you are
finished, click OK.
9. From the Verification panel, verify the data that represents the new host attachments. When
finished, click Finish.
