Troubleshooting

Snapprotect backup is failing

If multiple paths are available and multipath is not configured properly SnapProtect backup job may fail due to intermittent path failures. In case of improper multipath configuration, the SnapProtect backup chooses preferred path while performing mapping but preferred path may change due to failovers. Verify if the array you are using supports multi paths.

Unable to configure LSI array from OEM vendors

If you are unable to configure LSI array from OEM vendors, such as Dell, IBM, etc., make sure to set the LSI_VENDOR_NAME and LSI_PRODUCT_ID registry keys on the source and proxies if available.

How Can I Authenticate LSI Array Password with SMIS Server Password?

You can authenticate the LSI array password with SMIS (Storage Management Initiative Specification) server using CvSMISTool for successful snap creation.

Use the following steps to set the password:

1. From the command prompt, navigate to <Software Installation Directory>\Base folder.
2. Type CvSMISTool.exe.
3. Type 2 to set the password.

   1) Test SMIS Server
   2) Set LSI Array Password
   Select option 1 or 2, for Quit, default [1]: 2

4. Specify host name or IP address of the device manager where the array is configured.

   Enter SMIS server HostName or IP : <Server_Name>

5. Specify the user name of the SMIS server.

   Enter SMIS server User Name : <User Name>

6. Specify password for SMIS server.

   Enter SMIS server Password : <Password>

7. Specify the number corresponding to the array that you wish to select and press Enter.

   1) Array Name : iscsi-lsi-1
   Array UUID : *******1A2X
   
   2) Array Name : san_nas_lsi
   Array UUID : *******26B4
   Select option : [1 - 2] to quit, default [1]: 1

8. Specify password of LSI Array.

   Enter LSI Array Password:
   Re-enter LSI Array Password:

Best Practices

• Ensure that enough disk space is available for snapshot operations and the disk space used by snapshots is monitored. The space requirement for snapshots created during SnapProtect backup can vary based on your environment. The space utilization is dependent on the number of snapshots created and the retention period defined for the snapshots.

• While Volume Copy operation is in progress, read-write to the source volume should be frozen until volume copy operation completes.

• In order to use a specific initiator for accessing snapshots during SnapProtect backup set the sSNAP_UseINITIATOR registry key to the desired initiator address.
