Modify a CHAP User Account

For increased security, you may want to change the CHAP secret at regular intervals, or if you suspect that an unauthorized computer has accidentally gained access to the array.

NOTE: If you change a CHAP secret, all volumes protected with this CHAP account will be inaccessible until the corresponding iSCSI connections are changed and synchronize with the new CHAP secret. Consider this when you determine what time to make these changes.
  1. Go to Manage → Data Access → CHAP Accounts.
  2. Select the CHAP user whose CHAP secret you want to modify.
  3. Click the pencil icon to edit the CHAP account. Enter the new CHAP secret.
    CHAP secrets must be between 12 and 16 characters, can not contain [ ] & ; or `, and are case sensitive.
  4. Click OK.
  5. Use your iSCSI initiator software to change the CHAP secret to the iSCSI initiator configuration. The method used to add the CHAP secret to the iSCSI initiator is based on your OS and iSCSI management tool.
