SE commands overviewSE commands are available only to authorized Data Domain and partner supportpersonnel. These commands are not available or visible to sysadmin users. Thesecommands are not documented for customers because improper use of thesecommands can result in system downtime, data unavailability, or data loss. Do notprovide any listing of the SE commands for a customer to see.

smnp_debugsnmp debug-level set {none | packet | error | all}Provides debug options for the SNMP component. This command allows debug levelsof none, packet, error, and all. The "none" turns off additional debug information."Packet" provides the input and output packets in a readable format. "Error" is anintermediate level and only shows output errors. All is a verbose level that displays allpossible information.

You can display debug information by using the log watch as shown in the followingexample:

log watch debug/sm/snmpd.log 2015-12-21 10:23:12 NET-SNMP version 5.4.2.1 2015-12-21 10:23:28 Received SNMP packet(s) from UDP: [127.0.0.1]->[127.0.0.1]:47393

Once the required information is retrieved, you should reset the debug level back tothe default ("none"). In addition, you should monitor the size of thefile /ddr/var/log/debug/sm/snmpd.log to ensure it is not too large. If the file istoo large, you can disable the snmp service, delete the file, and then reenable theservice. Role required: admin, limited-admin.

snmp debug-level showShows the current debug status. Role required: admin, limited-admin.

vdisk Static-Image-Replication Steps

Replicating a vdisk static image is a multistep process that requires actions on boththe source and destination Data Domain systems. This appendix covers those steps inmore detail.

l vdisk static-image-replication steps...................................................................50


vdisk Static-Image-Replication Steps 49

vdisk static-image-replication stepsvdisk provides more detail about the vdisk static-image commands. Completethe following steps to execute a complete static image replication session:

Procedure

1. On the source Data Domain system, run the vdisk device createcommand to create a vdisk device.

2. On the source Data Domain system, run the vdisk static-image createcommand to create a static image of the new vdisk device.

3. On the destination Data Domain system, run the vdisk static-image-replication prepare source command to prepare the static image forreplication.

Record the vdisk replication id and vdisk destinationreplication copy-phase-seed values.

4. On the source Data Domain system, run the vdisk static-image-replication start command, with the values generated in step 3.

5. On the source Data Domain system, run the vdisk static-image-replication show status command.

The system displays Static-image-replication completedsuccessfully for the remote-replication id: <replication-id> when the replication is complete.

Note

Do not run this command on the destination Data Domain system. It will fail withthe error Failed to get status: Operation handle not found.

6. On the destination Data Domain System, run the vdisk static-image-replication finalize command to finalize the static image replication.

7. On the source Data Domain system, run the vdisk static-image-replication show status command.

The finalized replication system should not appear in the list of active sessions.The vdisk static-image-replication show status command clearsall completed static image replication sessions from the list of active sessions.
