  • storwize-v3500: IBM Storwize® V3500
  • storwize-v3700: IBM Storwize V3700
  • storwize-v5000: IBM Storwize V5000
  • storwize-v7000: IBM Storwize V7000 or IBM Storwize V7000 Unified
  • flashsystem-v9000: IBM FlashSystem V9000
  • flashsystem-v840: IBM FlashSystem V840
  • svc: IBM SAN Volume Controller
  • flashsystem-a9000: IBM FlashSystem® A9000
  • flashsystem-9100: IBM FlashSystem 9100

  • xiv: FlashSystem/IBM Spectrum Accelerate
-ip ip_address [;ip_address]
Specifies the IP address or host name of the clusters or nodes that are used by the storage system.
The following storage systems use two clusters. You must specify the IP address or host name for each cluster by using a semicolon between the addresses (for example, 192.0.2.0;192.0.2.1):
  • TotalStorage Enterprise Storage Server Model 800
  • IBM DS8000
The following storage systems use one node and require only one address or host name:
  • SAN Volume Controller
  • Storwize V3500
  • Storwize V3700
  • Storwize V5000
  • Storwize V7000
  • Storwize V7000 Unified
  • FlashSystem V9000
  • FlashSystem V840
  • FlashSystem 9100
  • FlashSystem 9200
The XIV® and FlashSystem A9000 use multiple nodes. Specify the IP address or host name for one node and the remaining nodes are discovered automatically.
Tip: To list the IP address of storage system clusters or nodes, use the lsdevice command.
-username user_name [;user_name]
Specifies the user name for the clusters or nodes that are used by the storage system. Enter the user name or user names that you want to change. If you want to change passwords associated with user names (but not the user names), enter the currently valid user names.
For the following storage systems, you can provide one user name, which is used for both clusters, or you can specify two user names. If you have separate user names, include a semicolon between the user name for cluster 0 and cluster 1.
  • TotalStorage Enterprise Storage Server Model 800
  • IBM DS8000
For the following storage systems, provide one user name:
  • SAN Volume Controller
  • Storwize V3500
  • Storwize V3700
  • Storwize V5000
  • Storwize V7000
  • Storwize V7000 Unified
  • FlashSystem V9000
  • FlashSystem V840
  • FlashSystem A9000
  • FlashSystem 9100
  • FlashSystem 9200
  • FlashSystem/IBM Spectrum Accelerate
-password password [;password]
Specifies the passwords for the user names. If you want to change user names, but do not want to change the passwords that are associated with the user names, enter the current passwords. If you do not include this parameter, you are prompted for the passwords.

Example: Changing user names and passwords

The following command shows how to change the IP address or host name and port number for a host system connection. The following output is returned:
Please enter a password for the device cluster 0 userid of admin:
