Performing Tasks With the CLI |
This chapter provides examples of how to perform tasks using a series of CLI commands.
TABLE 2-1 identifies the sequence of CLI commands used when registering arrays with Sun Storage Common Array Manager.
1. Identify the names of the arrays currently registered with Sun Storage Common Array Manager.
sscs list storage-system Array: Snoopy1 Array: Snoopy2 Array: Linus1
| Note - The command list devices can also be used to identify the names of arrays currently registered with Sun Storage Common Array Manager. |

The following information provides an overview of the CLI commands used for the T10 protection information (PI) feature. Further information concerning T10 PI, including requirements for using the feature, can be found in the CAM online help (within the browser interface) or in the Sun Storage Common Array Manager Array Administration Guide.
The following topics are discussed:
| Note - The below syntax may not represent all available options. Consult the complete command syntax by following the link for each stated command. |
Protection Information is a feature of disks that may not be modified. You can view PI capability of a disk by issuing the list disk command:
list -a <array-name> disk <disk-name>
In this example, the storage1 array is asked to report a list of its disks. In the below output, three disks are reported. Notice the Protection Information line. Two disks have PI capability (t0d02, t0d03), one does not (t0d10).
sscs list -a storage1 disk Tray: 0 Disk: t0d02 Capacity: 558.912 GB Type: SAS Speed (RPM): 10020 Status: Optimal State: Enabled Role: Unassigned Mirror Disk: - Virtual Disk: - Firmware: 0804 Serial number: 001022P15D8A PPG15D8A WWN: 20:00:00:00:C9:9F:5E:1F:00:00:00:00:00:00:00:00 Security Capable: None Security Enabled: Disabled Disk Locked: False Security Key Id: - Protection Information: Capable Tray: 0 Disk: t0d03 Capacity: 558.912 GB Type: SAS Speed (RPM): 10020 Status: Optimal State: Enabled Role: Unassigned Mirror Disk: - Virtual Disk: - Firmware: 0804 Serial number: 001022P15DEA PPG15DEA WWN: 20:00:00:00:C9:9F:59:D3:00:00:00:00:00:00:00:00 Security Capable: None Security Enabled: Disabled Disk Locked: False Security Key Id: - Protection Information: Capable Tray: 0 Disk: t0d10 Capacity: 279.396 GB Type: Fibre Channel Speed (RPM): 15015 Status: Optimal State: Enabled Role: Unassigned Mirror Disk: - Virtual Disk: - Firmware: 091C Serial number: 0910C19F7N 3QP19F7N WWN: 20:00:00:1D:38:D3:0E:C1:00:00:00:00:00:00:00:00 Security Capable: None Security Enabled: Disabled Disk Locked: False Security Key Id: - Protection Information: None
Virtual disks with Protection Information may be created by ensuring that all the disks that compose it are PI-capable. From the previous example, we know that disks t0d02 and t0d03 are PI-capable. To create a virtual disk, issue the create vdisk command:
create -a <array-name> -p <pool-name> -d <disk-name[,disk-name...]> vdisk <virtual-disk-name>
In this example, a PI-capable virtual disk named PI_vdisk is created using PI-capable disks on the storage1 array using the Default storage pool. Then, the list vdisk command is used to verify the new virtual disk.
sscs create -p Default -d t0d02,t0d03 -a storage1 vdisk PI_vdisk
sscs list -a storage1 vdisk PI_vdisk
Virtual Disk: PI_vdisk
Status: Optimal
State: Ready
Number of Disks: 2
RAID Level: 5
Total Capacity: 1.092 TB
Configured Capacity: 0.000 MB
Available Capacity: 1.092 TB
Array Name: storage1
Array Type: 6180
Disk Type: SAS
Security: Non-secure
Protection Information: Capable
Maximal Volume Size: 1.092 TB
Associated Disks:
Disk: t0d02
Disk: t0d03
To create a PI-enabled volume on a PI-capable virtual disk, the -i,--protection-information option must be specified using a create volume command variant supporting this option. For example:
create -a <array-name> -p <pool-name> -s <number<TB|GB|MB|KB|Bytes|BLK>> [-n <1..224>] [-d <disk-name[,disk-name...]>] [-c <A|B>] [-S] [-i] volume <volume-name>
In this example, a PI-enabled volume named vol1-PI is created on array storage1 using the Default storage pool and a 100MB volume size. Then, the list volume command is used to verify the new volume.
sscs create -a storage1 -p Default -s 100MB -i volume vol1-PI sscs list -a storage1 volume vol1-PI Volume: vol1-PI Type: Standard WWN: 60:08:0E:50:00:17:B5:22:00:00:49:8B:4D:8C:2B: 78 Pool: Default Profile: Default Virtual Disk: PI_vdisk Size: 100.000 MB State: Free Status: Online Action: Ready Condition: Optimal Read Only: No Controller: A Preferred Controller: A Modification Priority: High RAID Level: 5 Segment Size: 512 KB Read Cache: Enabled Write Cache: Enabled Write Cache with Replication: Enabled Write Cache without Batteries: Disabled Write Cache Active: True Flush Write Cache After: 10 s Disk Scrubbing: Enabled Disk Scrubbing with Redundancy: Disabled Security: Non-Secure Protection Information: Enabled Application Tag Ownership: Controller
The following additional PI-related tasks can be performed using the CLI:
|
Caution - This operation cannot be undone. Once disabled, PI cannot be re-enabled on an existing volume. To minimize accidental execution, only the long version of this option is provided. |
