Shared SAN Data Server - Troubleshooting

Mount Path Shared Using DataServer-FC or DataServer-iSCSI is Marked Offline

Symptom

A mount path shared using DataServer-FC is marked offline with the following reason;

 
[Mount path is inaccessible. Check the following.
 a. Is the mount path visible to the operating system on the MediaAgent machine.
 b. Is the username/password correctly entered.
 c. Does this user have read/write privileges to this mount path.]

Cause

A mount path shared using DataServer-FC may be marked offline if the services are stopped in the 'preferred' MediaAgent.

Resolution

1. From the CommCell Browser, expand to Storage Resources | Libraries | <Library>.

2. Right-click the mount path which is marked offline, and then click Properties.

3. Click the Sharing tab.

4. Note down the preferred MediaAgent. This is the MediaAgent in which the local path is displayed as an absolute path in the Path column. (The Path for the other MediaAgents will have the prefix FC.)

5. Login to this preferred MediaAgent.

6. Launch ProcessManager and then start the services. (See Start Services for step-by-step instructions.)

Troubleshooting - AIX Client when backing up to the SAN Data Server generates the “CONFIGURATION MISMATCH“ entry in errptTroubleshooting - AIX Client when backing up to the SAN Data Server generates the “CONFIGURATION MISMATCH“ entry in errpt

Symptom

When running AIX backups to the SAN data server, the following error entry is generated in errpt:

CONFIGURATION MISMATCH

Cause

This error message is generated due to the lack of vpd_map entry in the PdAt ODM database for the Luns exported from the SAN data server as the vpd_map for these devices are not part of the AIX operating system. This treats the drives as the "Other FC SCSI Disk Drive" and generates an entry for it in errpt .

Resolution

This error does not affect the AIX client backups or the functioning of the SAN data server.
