Snapshot Manager installation notes
The following list contains C installation information for RHEL, UNIX and Windows.
RHEL
Perform the following tasks for RHEL:
In the recent RHEL version, there are changes in usage of partition delimiter. Based on the last character in the device path, OS decides if partition delimiter must be added or not. To address the change, update the udev rule to add partition delimiter 'p' on RHEL.
Open the
/lib/udev/rules.d/62-multipath.rules
file.
Locate these line:
RUN+="$env{MPATH_SBIN_PATH}/kpartx -an $tempnode", \ ENV{DM_MULTIPATH_NEED_KPARTX}=""
Update the lines as follows:
RUN+="$env{MPATH_SBIN_PATH}/kpartx -an -p p $tempnode", \ ENV{DM_MULTIPATH_NEED_KPARTX}=""
Restart the multipath service, using the following command:
# service multipathd restart
For devices in LVM, if multiple paths are used, ensure that the multipathing service is enabled.
Junction mount point on filler or array is not supported for snapshot operations with VSO FIM snapshot method.
For client-side nested mount points, rollback of parent mount points is not supported.
UNIX
NetBackup Snapshot Manager is installed with the NetBackup client software. Every NetBackup server includes the NetBackup client software, by default. So, you can use NetBackup Snapshot Manager on a NetBackup server or client, if the Snapshot Manager is supported on that platform.
For NetBackup 10.1, Snapshot Manager for Solaris is supported on SPARC computers only.
For the NetBackup installation procedure, refer to the NetBackup Installation Guide
If you install in a cluster environment, first freeze the active node so that migrations do not occur during installation.
For information about freezing a service group, see the clustering section in the NetBackup High Availability Administrator's Guide for the cluster software you are running.
For Linux platform, ensure that sg3_utils package is installed.
When you install or upgrade the NetBackup Snapshot Manager, NetBackup deploys the
sg3_utils
package on the NetBackup Client.The package provides the rescan-scsi-bus.sh script which helps to rescan and discover new devices after a snapshot is imported. This script is used during 'bpfis import' and 'bpfis deport' operations. If this script is not present on the NetBackup client, snapshot import fails.
The default location of the script is:
<install_location>/usr/bin/rescan-scsi-bus.sh
In case, the package is not deployed run the following command:
yum install sg3_utils
For LinuX LVM, ensure that systemctl is available.
Ensure that F user is configured.
Windows
For Windows, NetBackup Snapshot Manager software is automatically installed with the core NetBackup server and client product.
For the NetBackup installation procedure, see the NetBackup Installation Guide.
If you install Snapshot Manager in a cluster environment, first freeze the active node so that migrations do not occur during installation.
For information about freezing a service group, see the clustering section in the NetBackup High Availability Administrator's Guide for the cluster software you are running.
Refer to the uninstall procedure that is described in the NetBackup Installation Guide
