Size (NWSSIZE)

Specifies the size of the network server storage space to be created.

*CALC

If the FROMNWSSTG parameter is *NONE, and a format of *NTFS is specified, the storage space size will be set to '2' MB. When *FAT32 is specified, the storage space size will be set to '512' MB. When *FAT or *OPEN is specified, the size will be set to '1' MB. When *NTFSQR is specified, the storage space size will be set to '500' MB.

If a valid network server storage space name has been specified in the FROMNWSSTG parameter, the new storage space will be created with the same size as the storage space specified in the FROMNWSSTG parameter.

1-1024000

Specify the size for the network server storage space, in megabytes.

The range for FORMAT types *NTFS, *FAT, *FAT32, and *OPEN is from 1 to 1024000 megabytes.
The range for FORMAT(*NTFSQR) is from 500 to 1024000 megabytes.

When a FROMNWSSTG network server storage space is specified, the NWSSIZE parameter must be set equal to or greater than the size of the network server storage space specified in the FROMNWSSTG parameter.

Format (FORMAT)

When a storage space is initially created, it is not formatted by the system. The storage space will need to be linked to a network server description and formatted by the hosted operating system.

*NTFS: The storage space should be formatted using Windows NT File System. Storage spaces created with this format can be linked to network server descriptions with connection types of *IXSVR, *ISCSI or *GUEST. This option offers the greatest benefit in a Windows server environment because of its better performance and integrated support of long filenames, larger disks, extended file attributes, file-security and recoverability features.
This option offers the greatest benefit in a Windows server environment because of its better performance and integrated support of long filenames, larger disks, extended file attributes, file-security and recoverability features. The size (NWSSIZE) parameter for a NTFS storage space must be at least 2 megabytes.
*FAT: The storage space should be formatted using the File Allocation Table file system. Storage spaces created with this format can be linked to network server descriptions with connection types of *IXSVR, *ISCSI, or *GUEST.
In most cases, however, greater efficiency and space utilization are achieved using the NTFS file system for Windows operating system types.
*FAT32: The storage space should be formatted using the 32-bit File Allocation Table file system. Storage spaces created with this format can be linked to network server descriptions with connection types of *IXSVR, *ISCSI, or *GUEST.
It includes support of long filenames and larger disk sizes. The size (NWSSIZE) parameter for a FAT32 storage space must be at least 512 megabytes.
*OPEN: The storage space should be formatted with an open file source file system. Storage spaces with this format can be linked to network server descriptions with Linux or AIX operating systems only.
*NTFSQR: The storage space should be formatted using Windows NT File System. Storage spaces created with this format will contain special attributes which makes it only linkable as a quorum resource disk used for Windows clustering.

Auxiliary storage pool ID (ASP)

Specifies the auxiliary storage pool (ASP) that will contain the new network server storage space.

Note: You cannot specify a value for both the ASP and ASPDEV parameters.

'1': The network server storage space is created in the system auxiliary pool ASP 1.
ASP-number: The network server storage space is created in user auxiliary storage pool 2-32 or in independent auxiliary storage pools 33-255.

ASP device (ASPDEV)

Specifies the name of the auxiliary storage pool (ASP) device where storage is allocated for the network server storage space.

Note: The ASP must have been activated (by varying on the ASP device) and have a status of 'Available'.

Note: You cannot specify a value for both the ASP and ASPDEV parameters.

ASP-device-name: The device name of the ASP to use for the network server storage space.

Cluster port configuration(CLUPORTCFG)

Specifies the TCP/IP configuration values that are specific to the cluster service. This information consists of three parts including the identification of the cluster connection port, the cluster internet address, and the cluster subnet mask.

Note: This parameter is required when FORMAT(*NTFSQR) is specified.

Element 1: Connection port

Specifies the virtual ethernet port to be configured for this cluster. This connection will be used as a private cluster connection between each cluster node.

Element 2: Cluster internet address

Specifies the internet address of this cluster. The internet address is specified in the form, nnn.nnn.nnn.nnn where nnn is a decimal number ranging from 0 through 255. An internet address that has a binary value of all ones or all zeros for the network identifier (ID) portion or the host ID portion of the internet address is not valid.

Element 3: Cluster subnet mask

Specifies the subnet mask associated with cluster internet address. Subnetting provides the capability to partition an internet domain. Specify the mask for the network subnet and host address fields of the internet address that defines a subnet. The subnet mask is in the form, nnn.nnn.nnn.nnn, where nnn is a decimal number ranging from 0 through 255.

Examples

Example 1: Create NTFS-format Storage Space

CRTNWSSTG   NWSSTG(STGSPACE3)  NWSSIZE(200)  FORMAT(*NTFS)

This command creates a network server storage space called STGSPACE3 with a size of 200 megabytes. The storage space will not be formatted and must be linked to a network server description with a connection type of *IXSVR, *ISCSI or *GUEST.

Example 2: Copy Existing Storage Space

CRTNWSSTG   NWSSTG(STGSPACE4)  NWSSIZE(*CALC)
            FROMNWSSTG(FROMSTG)  ASP(3)

This command creates a network server storage space called STGSPACE4 with a size and format the same as FROMSTG and copies the contents into STGSPACE4. It will be created in user auxiliary storage pool (ASP) 3.
