Storage Direct agent limitations and troubleshooting
Review the following limitations that apply to
PowerProtect Data Manager support for the Storage Direct agent.
Backup or any centralized operation might fail in Storage Direct agent versions 19.4 and earlier due to DD Boost and vDisk passwords being obtained from lockbox
In the Storage Direct agent versions 19.4 and earlier, the DD Boost and vDisk passwords are obtain from the lockbox instead of from
PowerProtect Data Manager. If using one of these versions and the backup or any centralized operation fails, you can add the passwords into the lockbox by running the following commands, and then retry the failed operation:
where
configFileName is the
protection policy name.config. For example,
sgpolicy2.config.
Asset configuration file must be provided during update for existing users
For existing Storage Direct agent users who are updating, the asset configuration file must be provided during the update. No option is provided to add the file once the update is completed.
Coexistence of the Storage Direct agent with other application agents is not supported
PowerProtect Data Manager does not support the coexistence of the Storage Direct agent with other application agents, such as the Oracle, SAP HANA, or SQL application agent in
PowerProtect Data Manager.
Configuration Change Management not supported for existing Storage Direct users
The Configuration Change Management feature is not supported for existing Storage Direct users updating to the Storage Direct agent for
PowerProtect Data Manager.
SDFSA install/update fails on trying to install using absolute path
An SDFSA installation or update fails when performed using the absolute path. For example:
Installation using absolute path
[root@xxxxx /]# /Softwares/builds/sdfsa_19.x_36/install.sh
2019/09/18 23:18:42 adm-agent rpm not found in current working directory...
Update using absolute path
[root@xxxxx sd_cfs]# /Softwares/builds/sdfsa_19.x_40/install.sh -u
2019/09/17 01:49:35 storagedirectagent rpm not found in current working directory...

/Softwares/builds/sdfsa_19.x_40/install.sh: line 601: [: -gt: unary operator expected
2019/09/17 01:49:35 storagedirectagent rpm not found in current working directory...
rpm -U --quiet --test
rpm: no packages given for install
2019/09/17 01:49:35 storagedirectagent upgrade failed...
2019/09/17 01:49:35 storagedirectagent upgrade failed...
To work around this issue, change the directory to the location of
install.sh and run
./install.sh.
Encapsulation fails during policy creation if a retention lock exists on VMAX or SMIS services that are not running
When a protection policy is created, a process that is called encapsulation occurs, which creates backup and restore FTS devices on the VMAX system and links the DD vDisk with FTS. If a retention lock exists on the VMAX system, or if the SMIS services are not running, encapsulation fails.
To ensure that there is no retention lock on the VMAX system, run the following command as the root user from the SMIS server:
symcfg list -lockn all
The output is similar to the following:
S Y M M E T R I X L O C K S
Lock Lock Lock Time
SymmID Attachment Status Number Usage Held (Sec)
000196700638 Local Locked 15 Config Change 13572 -> Almost 4 hours
000192604348 Remote N/A N/A N/A N/A
000297000476 Remote N/A N/A N/A N/A
If SMIS services are not running, an exception appears in the logs indicating that the
storsvd service is not available and a connection to SMIS cannot be established using the SYMAPI calls. If this exception occurs:
Run the following command as the root user from the SMIS server to verify the status of
storsvd:
./stordaemon show storsrvd
If the service is unavailable, the message
*** Daemon storsrvd is not currently running appears.
Restart the service by running
./stordaemon start storsrvd.
Run the
./stordaemon show storsrvd command again to verify that the status is now
Running.
To view the remote server details, run
./stordaemon action storsrvd -cmd show server.
To view the network configuration, run
./stordaemon action storsrvd -cmd show -netinfo.
Restart of encapsulation fails
When an encapsulation job for the Storage Direct agent does not complete successfully, a restart of the job in the
PowerProtect Data Manager UI fails with the message
error: Data Domain vDisk pool not provided remediation: null.
Encapsulation fails with error "SYMAPI_C_NET_HANDSHAKE_FAILED"
If the encapsulation of a device fails with the error
SYMAPI_C_NET_HANDSHAKE_FAILED:
Ensure that proper name resolution can occur by verifying that the
PowerProtect Data Manager server/SMIS server and SDA host are resolvable by either DNS or the hosts file.
Perform the following steps to ensure that the
PowerProtect Data Manager server can obtain all the necessary information from the SMIS server:
Log in to
PowerProtect Data Manager as an administrator.
Go to the
/usr/emc/API/symapi/config/netcnfg directory.
Verify that the server entry exists. For example,
<ConnectionName> - TCPIP <hostname> <ipaddress> 2707 -.
Verify whether the Solutions Enabler base daemon is running. For example:
admin@xxxxx:~> stordaemon list -all
Available Daemons ('[*]': Currently Running, '[NI]': Not Installed):
[*] storapid EMC Solutions Enabler Base Daemon
storgnsd EMC Solutions Enabler GNS Daemon
storrdfd EMC Solutions Enabler RDF Daemon
storevntd EMC Solutions Enabler Event Daemon
[*] storwatchd EMC Solutions Enabler Watchdog Daemon
storsrmd EMC Solutions Enabler SRM Daemon
Export the environment variables
SYMCLI_CONNECT_TYPE=REMOTE and
SYMCLI_CONNECT= <ConnectionName>.
Run
symcfg list. The command output should display all VMAX and PowerMax systems that have been added to the SMIS server.
Configuration file validation fails when multiple storage group assets are selected for policy inclusion if the configuration file is not formatted correctly
When you select multiple storage group assets as part of a
VMAX Storage Group protection policy in
PowerProtect Data Manager, validation fails if the configuration file is not formatted correctly. For example, a configuration file with the following format might be pushed to the host:
To work around this issue, enclose
VMAX_FASTX_RESTORE_SG in a comment and remove
RESTORE_DEVICE_POOL and one of the entries for
RESTORE_DEVICE_GROUP from the comment.
MTree replication fails when adding replication stage for multiple protection policies if assets have the same user/vDisk pool
If an existing Storage Direct user has updated to the Storage Direct agent for
PowerProtect Data Manager and uses the same user/vDisk pool for protected assets to create multiple protection policies with a replication stage, an MTree replication job fails with an error similar to the following:
Unable to create DataDomain user xxxx, User xxxx already exists.
To work around this issue, manually add the secondary DD system details in the configuration file.
Replication not supported for assets in a Storage Group policy for existing Storage Direct users if replication is already configured for stand-alone agent
The addition of a replication stage as part of a Storage Group protection policy is not supported when you use
PowerProtect Data Manager to create a Storage Direct setup and then try to import it into another
PowerProtect Data Manager.
To update the Storage Direct agent, remove the secondary DD system details from the configuration file before importing it.
Storage Direct agent creates a new snapshot when restarting failed backup jobs in
PowerProtect Data Manager
If a backup fails and you restart the backup job, the Storage Direct agent creates a new snapshot and does not reuse the snapshot that was created during the failed backup. This is expected behavior, and the latest snapshot is used for the new backup.
Removing the parent storage group when a configuration file generated by
PowerProtect Data Manager is imported during a Storage Direct agent update
If a Storage Direct configuration file generated by one
PowerProtect Data Manager system is imported as an existing Storage Direct configuration file into a second
PowerProtect Data Manager system, the parent storage group is not created during asset configuration in the existing VMAX storage group protection policy.
Before you add the configuration file to the
appsetting file, complete the following steps:
Open the Storage Direct configuration file in an editor.
Set the
VMAX_FASTX_RESTORE_SG parameter to the restore storage group that is created by
PowerProtect Data Manager.
NOTE If there are multiple storage groups, enclose each entry in a comment. Ensure that you follow the format for multiple restore device groups and restore storage groups. The
PowerProtect Data Manager for Storage Direct Agent User Guide provides more information.
Remove the parent storage group in the configuration file.
Delete the parent storage group from the VMAX storage array by running the
symcli command.
