Description
This document contains examples of some commonly used sccli commands that can be used on a Sun StorEdge[TM] 3510 FC Array, Sun StorEdge[TM] 3511 SATA Array, or Sun StorEdge[TM] 33x0 SCSI Array.
  1. To create a logical disk
  2. To partition a logical disk
  3. To map a partition to a host channel


Steps to Follow
The three sccli sub-commands are as follows:
    > create logical-drive [raid-level] [disk-list]
    > configure partition [partition-id] [size]
    > map [partition-id] [channel].[target].[lun]

Examples of these commands

First, list the unused disks in the array to determine their channel and IDs. Use the show disks command. Here is an abbreviated sample output:

    sccli> show disks
Ch  Id      Size   Speed  LD     Status   IDs                      Rev
------------------------------------------------------------------------
2   2   68.37GB   200MB  NONE   FRMT     SEAGATE ST373307FSUN72G  0307
2   3   68.37GB   200MB  NONE   FRMT     SEAGATE ST373307FSUN72G  0307
2   4   68.37GB   200MB  NONE   FRMT     SEAGATE ST373307FSUN72G  0307
2   5   68.37GB   200MB  NONE   FRMT     SEAGATE ST373307FSUN72G  0307
2   6   68.37GB   200MB  NONE   FRMT     SEAGATE ST373307FSUN72G  0307
2   7   68.37GB   200MB  NONE   FRMT     SEAGATE ST373307FSUN72G  0307
2   8   68.37GB   200MB  NONE   FRMT     SEAGATE ST373307FSUN72G  0307
2   9   68.37GB   200MB  NONE   FRMT     SEAGATE ST373307FSUN72G  0307
2  10   68.37GB   200MB  NONE   FRMT     SEAGATE ST373307FSUN72G  0307
2  11   68.37GB   200MB  NONE   FRMT     SEAGATE ST373307FSUN72G  0307 

Creating logical drives

This creates a RAID-5 logical drive with 5 disks:

     > create logical-drive RAID5 2.3,2.4,2.5,2.6,2.7

This creates an NRAID logical drive with 3 disks:

     > create logical-drive NRAID 2.9,2.10,2.11

After creating a logical disk, run the show logical-drives command to find the LD-ID of the newly-created logical drive. For example:

     sccli> show logical-drives
     LD    LD-ID         Size  Assigned    Type     Disks Spare  Failed Status
-------------------------------------------------------------------------
ld0   2B4416E8  204.35GB  Primary     RAID5      5     0      0    Good
ld1   4747D39B   68.12GB  Primary     NRAID      1     0      0    Good
     ld2   530E5934   68.12GB  Primary     NRAID      1     0      0    Good
ld3   4A52C0E9  204.35GB  Primary     NRAID      3     0      0    Good

Configuring partitions

Configure 5 partitions on the logical disk with ID 4A52C0E9, each a different size:

     configure partition 4A52C0E9-00 100m
configure partition 4A52C0E9-01 2g
configure partition 4A52C0E9-02 512m
configure partition 4A52C0E9-03 1024m
configure partition 4A52C0E9-04 4g

Partition IDs are composed of the LD-ID (from the show logical-drives command) and a HEX value between 00 and 7F, separated by a dash. In version 3.x FW, this means a maximum of 128 partitions per LD. With version 4.x FW, the maximum number of partitions per LD was reduced to 32 (the number of LDs was increased from 8 to 32).

When running this command, the user will be prompted to respond to the following:

        Repartitioning may cause data to be lost.
Change partition table?

If the intention is to use this command in a script or a loop, use the --yes option. For example:

        sccli --yes [device] configure partition 4A52C0E9-00 100m

Mapping partitions to LUNs

Syntax:

        map [partition-id] [channel].[target].[lun]

The following example will map the given partition to channel 1, target 42 as LUN 0.

        map 4A52C0E9-3C 1.42.0

The channel and target values should already be set and can be found by running the command show channels. The lun number is a decimal value between 0 and 31.

Internal Comments
The released documentation is definitely lacking in the area of good examples.

Hopefully, this document can be incorporated into future versions of the sccli manual, but until then, this should suffice to be a helpful reference.
