Selecting Meta devices.Selecting Meta devices.

Once found the “LUN” (it mostly will be a Hyper, as we are talking in Symmetrix language), we will be able to view its contents.In this particular case, we are loking at a Meta, with 3 Hypers: One is the Meta head, the other two are meta devices. Note the M, as Meta head is marked with (M) and accompanied with the number of meta devices in it.Also, have in mind that Hypers are normally of two sizes (per standardization) 16.96 and 56.9966 Gygabytes.On the right hand, we can see the LUN properties. Listed is the Meta head, ID 087, 16.96GB, allocated, and within its total Meta device size, 50.87 (3 LUNS in total).


Meta Devices (cont.)Meta Devices (cont.)

Here the example is repeated, but with more LUNS or Hypers. Here we can see Meta head 5F4, with its 7 devices attached to it, making it a (M)7 of 135.64Gb total.

LUN LUN

To see the diference, we have listed a LUN here. You can appreciate that LUN B4A, has 5.62GB Size, and summarizes with the other LUNS, 11.24GB.LUNs are not the common standard for Symmetrix, as they do not use the disk completely as Hypers. Hypers use the cylinders of the disks, using even the lastest cylinder of the disks, avoiding to leave MBs in disuse as is usual in LUNs. That is why the 16.96 and 59.9966 sizes are so intrincanted.

In this spreadsheet we have the free / unmapped Hypers, filtered by size, device, etc.Documentation is always a must, as it will guide us for future configurations, as for systems recovery.

Select the device on the left and the HBA ports on the right. Hold control to select more than one.Alert messages will be displayed for each of the HBAs to which we are adding the device (hyper).

To check availability of addresses into this ports, run:symcfg list -sid 1098 -fa 08c -p 1 -addresses -availablesymcfg list -sid 1098 -fa 09c -p 0 -addresses -available



Here is a preview of how the devices (Hyper) will be presented (allocated) to the selected storage HBA port.You can change the Address presented to the host, for better administration. (some systems do not like hexa values.)Select the addresses with * from the list gathered before, from OS.

It can be necessary to add the LUN number for the host. This is obtained from command “symcfg -sid XX list -address -fa Xx -p x -available”; for HPUX, the values “VBUS TID LUN”give a number between the three of them (0 00 001=001), for the rest of OSs, the value under “LUN” column, is the final LUN address for the host in HEXA, that must be converted to DEC for the system administrator.

The process is similar to map. The only changes is the unmap/map modificator inside the file.


Masking.Masking.

To make the storage visible to the host, you must complete the LUN Masking steps. To do so, go to “Hosts” section in left pannel, right click on the desired host (host to which allocate the storage) and select “Masking > Modify Masking Configurations”. This will take you to the following screen.This can be also done from CLI, with the “symmaskdb” command.


Masking. (cont.)Masking. (cont.)

In this screen we will provide all the data needed to complete the masking.First select the ports (HBA ports) of the server to which attach the devices.


Masking.Masking.

Select both HBA’s WWPN on upper left box, choose storae array, and select type of device as desired. Finally, select the storage port to be assigned to.In bottom list, check the devices you will be adding, in pairs (as they are seen once per HBA port.)


Masking.Masking.

The is the completed list of tasks. Once we have this, click on “Grant” to execute the tasks.


Masking: disks that were previously allocated to a host.Masking: disks that were previously allocated to a host.

Note the differences between the marked devices: This is telling us that the disks were previously assigned to another host/s, but they maybe still allocated or not. Please it is very important for you to validate that you are not assigning a device for second time to the same or another host.The thin line represents one previous assignment, the thick line represents more than one previous assignment.The disks you normally will be assigning/allocating, should not have this “underscore” mark on the devices list.This list is an example, as you can also see that there are some devices with granted permissions to a host.

Here we masked device “xxx”to wwn “wwnxxx” by mapped port “Xx:x”. Then, we verified the configuration. This process is repeated for all devices needing to be masked to a wwn by a port, normally two ports and two wwn for resilience.When working with Celerrasystems, replace “–noprompt”with “–celerra”

The inq command, submits SCSI commands to inquire the Storage device, hence it is independent from OS. I will query and retriveall LUNS that are mapped and masked to corresponding systems and devices. If you see the LUN ID here, you should be able to configure it on the system. If it is not possible, check OS parameters or reboot.
