correct assignment of multipath priorities. HP recommends mapping all ports to each volume
to facilitate proper hardware failover.
a.

Create vdisks in the MGS and MDS array. The following example assumes the MGS
and MDS do not have attached disk enclosures and creates one vdisk for the controller
enclosure.

# formdsmsas create vdisk level raid10 disks 1.1-2:1.3-4:1.5-6:1.7-8:1.9-10 assigned-to a spare
1.11-12 mode offline vdisk1; done

Creating vdisks using offline mode is faster, but in offline mode the vdisk must be
created before you can create the volume. Use the show vdisks command to check
the status. When the status changes from OFFL, you can create the volume.

# formdsmsas show vdisks; done

Make a note of the size of the vdisks and use that number <size> to create the volume
in the next step.

Create volumes on the MDS and MDS vdisk.

# formdsmsas create volume vdisk vdisk1 size <size> volume1 lun 31 ports a1,a2,b1,b2; done

Create vdisks in each OST array. For OST arrays with three attached disk drive
enclosures, create four vdisks, one for the controller enclosure and one for each of the
attached disk enclosures. For example:

# forostmsas create vdisk level raid6 disks 1.1-11 assigned-to a spare 1.12 mode offline vdisk1; done

# forostmsas create vdisk level raid6 disks 2.1-11 assigned-to b spare 2.12 mode offline vdisk2; done

# forostmsas create vdisk level raid6 disks 3.1-11 assigned-to a spare 3.12 mode offline vdisk3; done

# forostmsas create vdisk level raid6 disks 4.1-11 assigned-to b spare 4.12 mode offline vdisk3; done

Use the show vdisks command to check the status. When the status changes from
OFFL, you can create the volume.

# forostmsas show vdisks; done

Make a note of the size of the vdisks and use that number <size> to create the volume
in the next step.

Create volumes on all OST vdisks.

# forostmsas create volume vdisk vdisk1 size <size> volume1 lun 41 ports a1,a2,b1,b2; done

# forostmsas create volume vdisk vdisk2 size <size> volume2 lun 42 ports a1,a2,b1,b2; done

# forostmsas create volume vdisk vdisk3 size <size> volume3 lun 43 ports a1,a2,b1,b2; done

# forostmsas create volume vdisk vdisk4 size <size> volume4 lun 44 ports a1,a2,b1,b2; done

Use the following command to display the newly created volumes:

# forostmsas show volumes; done

Reboot the file system servers to discover the newly created volumes.

2.4 MSA2000 Monitoring

The MSA2000 storage is a critical component of the HP SFS G3 system. Although the system has
many features to avoid single points of failures and is highly reliable, it is important to understand
how to monitor and verify the health of the system. If problem is suspected on one of the MSA2000
controllers, extensive information is available from the management interfaces. Some of the
important and frequently used CLI commands to check status are:

•

# show events

•

# show configuration

•

# show frus

This information is also available through the GUI. For complete information, see the MSA
manuals for your specific hardware.

To upload log information from the MSA2000 controllers to a Linux system using FTP:
