HP XP7 Disk Array Configuration Guide (H6F56-96003)
Fabric zoning and LUN security for multiple operating systems
You can connect multiple clusters with multiple operating systems to the same switch and fabric
using appropriate zoning and LUN security as follows:
• Storage port zones can overlap if more than one operating system needs to share an array
port.
• Heterogeneous operating systems can share an array port if you set the appropriate host
group and mode. All others must connect to a dedicated array port.
• Use LUN Manager for LUN isolation when multiple hosts connect through a shared array port.
LUN Manager provides LUN security by allowing you to restrict which LUNs each host can
access.

Connecting the disk array
The HP service representative performs the following steps to connect the disk array to the host:
1. Verifying operational status of the disk array channel adapters, LDEVs, and paths.
2. Connecting the Fibre Channel cables between the disk array and the fabric switch or host.
3. Verifying the ready status of the disk array and peripherals.
Restarting the Linux server
To recognize the new device(s), restart the Linux server as follows:
1. Power on the display of the Linux server.
2. Power on all devices other than the Linux server.
3. Confirm ready status of all devices.
4. Power on the Linux server.
Verifying new device recognition
Verify that the FCA driver is installed using the sr-probe command.
