Rubrik CDM module fails to restore from remote cluster on newer Rubrik releases

• ReaR version ("/usr/sbin/rear -V"):

• Description of the issue (ideally so that others can reproduce it):

When running rear recover with the CDM module the user is asked if they are recovering from the same Rubrik cluster. If they enter n and then type in the IP address of the new CDM cluster the recovery fails. The failure message indicates that the tar file cannot be unzipped.

The source of this problem is that the name of the tar file that is being downloaded has changed in Rubrik CDM v5.1.

• Workaround, if any:

Edit /usr/share/rear/verify/CDM/default/410_use_replica_cdm_cluster_cert.sh and change:

CDM_SUNOS_TAR=rubrik-agent-sunos5.10.sparc.tar.gz

to

CDM_SUNOS_TAR=rubrik-agent-solaris.sparc.tar.gz

• Attachments, as applicable ("rear -D mkrescue/mkbackup/recover" debug log files):

ERROR: Could not extract rubrik-agent-sunos5.10.sparc.tar.gz
gzip: stdin: not in gzip format
/usr/bin/tar: Child returned status 1
/usr/bin/tar: Error is not recoverable: exiting now

With #2445 merged
this issue should be somewhat fixed, cf.
#2445 (comment)

A better solution would be in default.conf a new array like

CMD_RBS_AGENT_FILES=( "rubrik-agent-solaris.sparc.tar.gz" "rubrik-agent-sunos5.10.sparc.tar.gz" )

and then in verify/CDM/default/410_use_replica_cdm_cluster_cert.sh code like

local cdm_rbs_agent_file
for cdm_rbs_agent_file in "${CDM_RBS_AGENT_FILES[@]}" ; do
    curl $v -fskLOJ https://$CDM_CLUSTER_IP/connector/$cdm_rbs_agent_file && break
done
