IBM Storwize Host Tasks

This chapter contains the following sections:

Create IBM Storwize Host

Summary
Create IBM Storwize Host
Description
This task creates a Host entry by using a WWPN/WWNN number of remote server. This task associates one or more HBA WWPNs or iSCSI names with a logical host object.
Inputs
Input Description Mappable To Type Mandatory

Port numbers should be separated by ','(In case of multiple port Port numbers should be separated by ','(In case of multiple port
Use CHAP Authentication (all ports) Use CHAPAuthentication( all ports) IBMStorwize​Boolean​List
Use CHAP Authentication Name Enter use CHAP Authentication name gen_​text_​input
I/O Group Choose an I/O group.​ The host can access volumes from one or more I/O groups.​ ibm​Storwize​Host​IOGroup​Identity Y
Host Type hoose a host type.​ Some hosts require a specific host type based on hardware or software requirements.​ For most hosts, you can use a generic type.​ ibm​Storwize​Host​Types Y
Outputs
Output Description Type

Delete IBM Storwize Host

Summary
Delete Host
Description
This task deletes the specified host. If the volumes are mapped to the host, forcing the deletion will make volumes no longer accessible to hosts.
Inputs
Input Description Mappable To Type Mandatory
Host Choose an IBM Storwize host to be deleted ibm​Storwize​Host​Identity Y
Delete hosts even if volumes are mapped to them.​ These volumes will no longer be accessible to hosts.​ Check to force delete for recursive deletion IBMStorwize​Boolean​List
Outputs
Output Description Type
IBM_​STORWIZE_​OUTPUT_​HOST_​IDENTITY Output of host identity ibm​Storwize​Host​Identity
IBM_​STORWIZE_​OUTPUT_​HOST_​NAME Output of host name gen_​text_​input

IBM Storwize Duplicate Mappings

Summary
Duplicate Mappings
Description
This task duplicates all the existing source host mappings to the target host. Volumes that are assigned to a host can be mapped to another host object. You can do this for example when you add a new node to the host cluster and want to ensure that the new host node has access to same set of volumes as the source host.
Inputs
Input Description Mappable To Type Mandatory
Host Choose an IBM Storwize host from which to duplicate mappings ibm​Storwize​Host​Identity Y
Target Host Choose an IBM Storwize target host to which to duplicate mappings ibm​Storwize​Host​Identity
Outputs
Output Description Type
IBM_​STORWIZE_​OUTPUT_​HOST_​IDENTITY Output of host identity ibm​Storwize​Host​Identity
IBM_​STORWIZE_​OUTPUT_​HOST_​NAME Output of host name gen_​text_​input
OUTPUT_​TARGET_​HOST_​NAME Output of target host name(s) gen_​text_​input

Import IBM Storwize Mappings

Summary
Import Mappings
Description
This tasks import existing source host mappings provided the target host has no existing mappings
Inputs
Input Description Mappable To Type Mandatory

Source Host Choose an IBM Storiwize source host from which to import mappings ibm​Storwize​Host​Identity Y
Outputs
Output Description Type

IBM_​STORWIZE_​OUTPUT_​SOURCE_​HOST_​NAME Output of source host name gen_​text_​input

Rename IBM Storwize Host

Summary
Rename Host
Description
This task assigns a new name for the specified host.
Inputs
Input Description Mappable To Type Mandatory
Host Choose an IBM Storwize host to rename ibm​Storwize​Host​Identity Y
Host Name Enter a name for the host gen_​text_​input Y
Outputs
Output Description Type

Unmap All IBM Storwize Volumes

Summary
Unmap All IBM Storwize Volumes
Description
This task unmaps all access that this host has to its volumes. A host is able to access only those volumes on your IBM Storwize system that are mapped to it. If you want to remove access to all volumes for one host, regardless of how many volumes are mapped to it, execute this task.
Inputs
Input Description Mappable To Type Mandatory
