PowerProtect Data Manager Appliance 5.16.0.0 Storage Array User Guide

Configuration job started due to change in PowerProtect Data Manager Appliance IP address fails

When you change a PowerProtect Data Manager Appliance IP address, the configuration job that starts during the discovery fails to update the remote system on the PowerStore array.

If this issue occurs, run the configuration job again.

Timeout error with /storage-hosts API when restoring using Instant Access

When performing an Instant Access restore, if you select either Map to Host or Map to Host Group on the Location page of the Block Volumes Restore wizard, a timeout error may occur. This issue might happen if there is a network connectivity issue between PowerStore and PowerProtect Data Manager Appliance. The issue can also occur if the PowerStore REST API is delayed in fetching the host details and sending a response back to the /storage-hosts API.

If this error occurs, the following message is displayed:

As a workaround, close the error message dialog and retry the operation.

Unable to update the remote system after changing the storage unit password

If you try to change the password of an existing storage unit in PowerProtect Data Manager Appliance while a backup is in progress, the backup job fails along with the array configuration job that is triggered by the storage unit password change.

The array configuration job fails with the following error even though the remote system is not in use by any protection jobs:

org.springframework.web.client.HttpClientErrorException$BadRequest:
400 Bad Request: "{"messages": [{"code":"0xE02010020086","severity":"Error","message_l10n":"Failed
to modify the remote system protection_policy1-ldpde105-b9ab3 due to associated active remote
sessions.","arguments":["protection_policy1-ldpde105-b9ab3"]}]}"

To resolve this issue, contact Customer Support.

Unable to complete data protection operations when a remote PowerStore system goes into "PARTIAL DATA CONNECTION LOSS" state

Backup, restore, and instant access operations for block volume protection policies cannot complete successfully when a remote PowerStore system goes into PARTIAL DATA CONNECTION LOSS state and does not instantly return to OK state.

This issue occurs primarily due to network connectivity disruptions, and can usually be resolved by maintaining a stable network. The PowerStore system typically returns to OK state without intervention. If the network is stable but the network error under the Connectivity tab of the remote system persists, and the remote system does not return to OK state within 10 to 15 minutes, contact Dell Customer Support.

Instant Access fails for backup and restore sessions that are in an In-Progress, Canceling, or Failed Cleanup Required state

Instant Access fails for backup and restore sessions that are shown as In-Progress, Canceling, or Failed Cleanup Required in PowerStore Manager.

To resolve this issue for Instant Access jobs that are shown as In-Progress or Canceling, wait until the job completes and then retry the Instant Access operation in the PowerProtect Data Manager Appliance UI.

To resolve this issue for Instant Access jobs that are shown as Failed Cleanup Required in PowerStore Manager and Failed in PowerProtect Data Manager Appliance, complete the following steps in the PowerProtect Data Manager Appliance UI:

1. Click in the Details column next to the job.

   PowerProtect Data Manager Appliance displays the error details and the steps to resolve the issue.

2. Complete the steps to resolve the issue, and then retry the Instant Access operation.

If an Instant Access job fails with the error message clean up in progress in PowerStore Manager, wait until the operation completes. Once the operation is complete, retry the Instant Access operation in the PowerProtect Data Manager Appliance UI.

During an initial discovery of a PowerStore asset source, PowerProtect Data Manager Appliance does not discover or protect empty volume groups

Volume groups that do not contain any volumes cannot be protected and are not discovered as part of the initial discovery of the asset source in the PowerProtect Data Manager Appliance UI.

If a volume group was added to a protection policy when it was not empty, but is now empty and a subsequent discovery is performed, the volume group is still shown in the list of assets in the PowerProtect Data Manager Appliance UI. Backups that are performed while the volume group is empty will fail with an error.

Empty volume groups can be kept when there are backups that were performed before the volume group was empty that might need to be restored. To restore data that was backed up before the volume group was empty, use Restore to alternate and select a different volume group as the target.

Protection operations fail intermittently when encryption in-flight is enabled from PowerStore

Enabling encryption in-flight on the remote system from PowerStore causes backups and restores to fail intermittently.

To resolve this issue, wait for the completion of the configuration job that was started when the option was enabled, and until the remote system returns to an OK state, and then retry the backup or restore operation.

Restore/Instant Access fails with Bad Request error when control path address is used

A restore/instant access fails with the following error when the control path address is used for the data path operation:

org.springframework.web.client.HttpClientErrorException$BadRequest: 400 Bad Request: "{"messages":[{"code":"0xE0201002008C","severity":"Error","message_l10n":"Operation failed on remote system. Verify the data transfer IP address or FQDN.","arguments":[null]}]}"

This issue impacts restore to original, restore to alternate, and instant access restores, regardless of the source site or backup site.

If there are assets that you want to restore that are no longer assigned to a protection policy, create a temporary policy in Disabled mode and add the assets to the policy that you want to back up and restore.

Unable to restore from replicated backups using Instant Access

Instant Access restores from replicated backup copies fail with the following error:

org.springframework.web.client.HttpClientErrorException$BadRequest: 400 Bad Request: "{"messages":[{"code":"0xE0204001002F","severity":"Error","message_l10n":"Instant Access/Retrieve operation failed because remote snapshot 89d298f5-ae7e-485b-934c-63e27b35d6c2 does not belong to the remote system 96c0782a-d228-4bb4-9bfb-1698a10e3d37.","arguments":["89d298f5-ae7e-485b-934c-63e27b35d6c2","96c0782a-d228-4bb4-9bfb-1698a10e3d37"]}]}"

Block volume Restore to Original might fail with error

A Restore to Original of a block volume might fail with the following error:

org.springframework.web.client.HttpClientErrorException$BadRequest: 400 Bad Request... Retrieve session already exists for a given resource

To resolve this issue, contact Dell Customer Support.

Internal Server error due to target protection storage user password or user account issue

During a storage array configuration, backup, or restore job, the following error might occur on the PowerStore system when the target protection storage user password is incorrect or the target protection storage user account has been locked or disabled:

org.springframework.web.client.HttpServerErrorException$InternalServerError: 
500 Internal Server Error: "{"messages":
[{"code":"0xE02010020082","severity":"Error","message_l10n":"Operation on
remote system failed due to internal error, try again. If the error persists,
contact your service provider for assistance."}]}"

If the cause of the error is an incorrect password, change the password using the following steps:

1. Change the target protection storage user password in the PowerProtect Data Manager Appliance UI.
2. Change the same password in the corresponding credential object.
3. Retry the job.

If the job continues to fail with the same error, the account might be disabled. Contact Dell Customer support for more information about the steps required to enable the account again.

Re-create a PowerProtect Data Manager Appliance user with the role user that has been accidentally deleted

A new target protection storage user with the role user is created as part of the configuration job for PowerStore block volume protection policies. The password for this user is managed by PowerProtect Data Manager Appliance, and the name of this user is in the format user_ targetStorageName_UniqueIdentifier. If this user is accidentally deleted, then you can re-create this user with the same username credentials. In the PowerProtect Data Manager Appliance UI, go to Administration > Credentials to obtain the user name.

• If the target protection storage is a DM5500 system, create a local user from the PowerProtect Data Manager Appliance UI. Go to Administration > Access Control > Users/Groups and click Add User/Group. Ensure that the user has the role user.
• If the target protection storage is a DDor DDVE system, log in to the DDOS to create a user with the role user.

After re-creating the user, ensure that you change the password in the corresponding credentials object, and maintain the same password in the PowerProtect Data Manager Appliance UI. Go to Administration > Credentials, select the user, and click Edit to update the password.

If the target protection storage is a replica DM5500 system, then log in to the source DM5500 system after you create the user on the replica DM5500 system, and add the corresponding credentials in the source DM5500 system.
