Command to create ACLX device

Hi,

I will assume you are referring to a VMAX array with 5874 code and above and Solutions Enabler 7.6. With VMAX arrays, the ACLX is usually created in the BIN upon initial load. It might not be mapped to your FA's for security reasons, but it should still be created in the BIN. If you have already queried your array for the ACLX device and haven't found it, you can create a new one with the "create dev" command:

create dev count=n,

size=n [MB |GB | CYL],

emulation=EmulationType,

config=DeviceConfig,

[, data_member_count=nn]

[, remote_config=DeviceConfig,

remote_data_member_count=nn,

ra_group=n, [remote_mvs_ssid=nnn],

[dynamic_capability=[dyn_rdf | dyn_rdf1_only | dyn_rdf2_only]]

[, mvs_ssid=nnn]

[, attribute=ckd_meta | savedev | datadev

[in pool PoolName] [member_state=ENABLE | DISABLE] ]

[meta_member_size = [MB | GB | CYL]]

[meta_config = [striped | concatenated]][, disk_group=nnn|

name:DskGrpName,

[remote_disk_group=nnn | name:DskGrpName] ],

[, binding to pool=PoolName

[preallocate size = ]

[allocate_type = persistent]

[remote_pool=PoolName]]]

[, [mapping to dir DirNum:PortNum

[starting] target = scsi_target,

lun=scsi_lun, vbus=fibre_vbus

[starting] base_address= ]...]

[[device_attr =

[SCSI3_persist_reserv | ACLX |DIF1 |AS400_GK]]...]

[,device_name=DeviceName

[,number= ]];

It would look something like this:

symconfigure -sid XXX -cmd "create dev count=1, size=6 cyl, emulation=fba, config=2-way-mir, device_attr=ACLX;" preview/commit

Usually the ACLX is 6 cylinders in size - sometimes a little larger, but it doesn't consume much space. I believe it is required to be a thick device and mirrored so that is why the config is set to 2-way-mir.

Note - the device_attr of ACLX is only for VMAX arrays at 5874 and above, If you are talking about a 5773 or lower code revision, the attribute would be "vcmdb"

Hi, Thank you for Answer to my query ....

Have small doubt here. If we setting up new VMAX array, ACLX is should be create & will login right ?or how will login 1st time to setup the VMAX array ..? Plz

If this is a new array, ACLX should have been created in the BIN file already. Most likely the FA's will have the ACLX bit set and the ACLX device is mapped to the FA's. If that is the case, then all servers zoned to those FA's with the ACLX device mapped to it should rescan and see the ACLX device to be used.

If, for security and best practices reasons, the ACLX is only mapped to a subset of the FA's, then only servers zoned to those FA's will be able to utilize the ACLX device....all other FA's will not display the ACLX device upon rescan.

For a brand new install, usually it is known what FA(s) the ACLX device is mapped to (you can tell this by reading the BIN file or asking the EMC CE). After the array is powered on, a management host is usually zoned to those FA's to see the ACLX and start the initial configuration of the array. If the ACLX device is not mapped to any FA's, the you would need to perform that configuration through the BIN file prior to setting up the array or have EMC utilize the service processor to perform the mappings for the ACLX device so that the hosts in your enviornment could utilize it.

Hi,

That answer could depend on alot of items, but at a really high-level this would typically be the steps:

1. EMC Solutions Architect and CE design and create the BIN with customer input - this would account for the ACLX creation and how it is mapped to the FA's

2. EMC CE would rack/initialize the array.

3. Assuming Unisphere and all that is setup on a host that can now be zoned to an FA on the new array that also has the ACLX mapped to the FA and enabled in the director settings, the Unisphere host should see the ACLX device through Solutions Enabler

4. At this point, the Storage Admin or EMC Implementation Specialist would then proceed to create and configure all additional needs (host connections, replication, auto-provisioning groups, etc).

Hi, Thank you for Answer to my query. Could you please explain me about the below.

Please explain me, How to setup New VMAX Array install & setup ? End to End

Means...

Whats steps performed by EMC Engineer & Whats steps Storage Admin performed.

If explain me step by step thats really helped out.

Thank you

Unisphere can also be enabled to run on the service process, no need to have a dedicated host.

Good catch. If you really wanted you don't even need UNI...just CLI all day long from Solutions Enabler. Things have changed a bit in VMAX3 as well....so I am assuming a VMAX1/2 here
