60 Assigning disks and array LUNs to the gateway
Assigning disks and array LUNs to the gateway
Assigning
ownership of disks,
array LUNs, or both
Automatic disk assignment is enabled for disks by default. If you have disabled
this feature, you must manually assign disk ownership for disks. Automatic disk
ownership does not apply to array LUNS. To assign ownership of disks, array
LUNs, or both to the gateway, complete the following steps.
Note
With the
disk assign
command, using the
-T
parameter in conjunction with the
-n
count parameter enables you to specify the number of disks of a particular
type—or array LUNs—that you want to assign. Adding the
-X
parameter aligns
the columns in the output—for example,
disk assign -T
disktype
-x
.
Step Action
1 Use the following command:
disk assign { disk_name | all | -n count | -T disktype }
[-p pool ] [-c block|zoned]
disk_name |
all
|
-n
count : Required option. Identifies the disks and
array LUNs assigned to this gateway. Parameters are as follows:
◆
disk_name specifies, by disk name or array LUN name, the disks
or array LUNs to be assigned. In most cases, you identify the
name of the specific disks or array LUNs that this gateway is to
own in either of following formats:
disk assign fullLUNname1 fullLUNname2 ...
disk assign fulldiskname1 fulldiskname2 ...
◆
all
causes all disks and array LUNs that were made available on
the storage array to gateways to be assigned to this gateway.
◆
-n
count causes the number of unassigned disks and array LUNs
specified by count to be assigned to this gateway.
If, for example, you enter
disk assign -n 5
, Data ONTAP
assigns three disks and two array LUNs.
◆
-T
, when used with
-n
count , specifies the “disk type.” Valid
types for the
-T
option are ATA, EATA, FCAL, LUN, SAS,
SATA, SCSI, XATA, XSAS.
