View and Modify Existing Storage Allocations (CLI)

Language:

Before You Begin

Ensure that your chassis hardware configuration meets the requirements in Chassis Hardware Requirements.
Admin (a) role privileges in Oracle ILOM are required to view and modify the Sun Blade Zone Manager properties.
The Sun Blade Zone Manager must be enabled in Oracle ILOM.

Access the Sun Blade Zone Manager from the CLI.
See Access and Enable Sun Blade Zone Manager .

To view storage resources allocated to a CPU blade server, perform one of the following.
- To view the storage allocations for a CPU blade server, use the show command followed by the /STORAGE/sas_zoning/BLn target. For example:
```
-> show /STORAGE/sas_zoning/BL0 
 
   Targets: 
      0     (/CH/BL2/HDD0)
      1     (/CH/BL2/HDD1)
```
  In this example, the HDD0 and HDD1, which are currently installed in the storage blade server in chassis slot 2, are allocated to the CPU blade server in chassis slot 0.
- To view where a storage blade resource is allocated, use the show command followed by /STORAGE/BLn/HDDn target. For example:
```
-> show /STORAGE/BL2/HDD0
 
   Targets: 
      0     (/CH/BL0)
 
-> show /STORAGE/BL2/HDD1
 
   Targets:  
      0     (/CH/BL0) 
```
  In this example, the resources HDD0 and HDD1, which are installed in the storage blade server in chassis slot 2, are assigned to the CPU blade server in chassis slot 0.

To modify the storage allocations, perform one of the following methods:
Method 1: Add or unassign storage resources per CPU blade server.
- To assign a storage resource to a CPU blade server, type:
  
  -> cd /STORAGE/sas_zoning/BLn-> set add_storage_access=path_to_storage_device
  
  Where BLn is the CPU blade server chassis slot location, and path_to_storage_device is the path to the storage blade resource.
- To unassign a storage resource from a CPU blade server, type:
  
  -> cd /STORAGE/sas_zoning/BLn-> set remove_storage_access=path_to_storage_device
  
  Where BLn is the CPU blade server chassis slot location, and path_to_storage_device is the path to the resource on the storage blade server. For example, /CH/BL1/HDD0.
Method 2: Add or unassign server blade access to storage device.
- To assign a CPU blade server to a storage resource, type:
  
  -> cd /STORAGE/sas_zoning/BLn/HDDn
  
  -> set add_host_access=path_to_blade_server
- To unassign a host server blade access to a storage device, type:
  
  -> cd /STORAGE/sas_zoning/BLn/HDDn
  
  -> set remove_host_access=path_to_blade_server
Where BLn is the storage blade server chassis slot location, HDDn is the storage resource slot location, and path_to_blade_server is the chassis slot location for the CPU blade server that you want the resource assigned or unassigned. For example, /CH/BL0.

Note - You can also add or unassign multiple storage devices in a single command line. To do so, specify the full path to the resource and separate each resource with a comma (no space). For example: -> set add_storage_access=/CH/BL1/HDD0,/CH/BL1/HDD1

Back up the blade storage group assignment.
