Start the customized installation process for a
PowerFlex system.
Prerequisites
Ensure that the software packages and CSV file have been successfully uploaded to the
PowerFlex Installer.
If LIA authentication will be LDAP-based, configure all items required for LDAP support that are described in the
Dell PowerFlex User Roles and LDAP Usage Technical Notes.
If LIA authentication will be LDAP-based, and the LDAP service is Linux-based, ensure that the
gatewayUser.properties file is configured with the parameters for
lia.ldap.initial.usernameDnFormat and
lia.ldap.initial.searchFilterFormat. Ensure that the same CN (user), OU (organizational unit) and DC (domain) parameters are configured in that file, and in the appropriate step in this procedure.
Steps
On the
Installation Configuration page,
Credentials Configuration section, for
MDM Password, enter a new MDM password in the
password field, and enter it again in the
confirm password field.
The MDM password is a password that is configured for the MDM during the installation. It must meet the following criteria:
Between 6 and 31 ASCII-printable characters
Includes at least 3 of the following groups: [a-z], [A-Z], [0-9], special chars (!@#$ …)
Contains no white spaces
For
LIA Authentication, select
Native for local authentication, or
LDAP for LDAP authentication.
NOTE: When using the
PowerFlex Installer to extend (rather than to install) a system, enter the LIA credentials that you entered during the initial installation.
If you selected
Native, for
LIA Password, enter a password in the
password field, and enter it again in the
confirm password field.
The LIA password is a new password that will be used to authenticate communication between the
PowerFlex Installer and the Light Installation Agent (LIA). It must meet the same criteria as the MDM password, as listed in the previous step.
If you selected
LDAP, you can add the credentials for one LDAP server. After deployment, up to seven more LDAP servers can be added. For more information, see the
Dell PowerFlex User Roles and LDAP Usage Technical Notes.
Enter the required information in the additional fields that are displayed:
Review the end user license agreement and select the check box to accept the license agreement.
For complete information on licensing, see the "Licensing" section of this guide.
Advanced options can be configured now. The following list describes the available options. Click
Set advanced options to access these options and configure them.
Option type
Option
Description
Skip options
Skip upload
Do not upload packages. You can use this if the packages were already uploaded.
Skip installation
Do not install packages. You can use this if the packages were already installed.
Skip configuration
Do not configure
PowerFlex components. You can use this option if you only want to upload and install packages now.
Skip Linux devices validation
Do not validate Linux device names.
Use case: during the
PowerFlex Installer validate stage, errors in the entering of Linux device names (such as
/dev/sdbb instead of
/dev/sdb) will prevent the continuation of the installation. This can be a problem if you want to add valid devices that do not meet the
/proc/partitions standard (such as aliases and logical names). Therefore, when this option is selected, the validate stage will be completed, but the affected node will show a completed (warning) status. You can click
Details to see the error, and you can choose to proceed with the installation. Continue with the remainder of the installation procedures.
Configuration options
Enable alert service and create lockbox
Enable the alert service required for SNMP and Secure Remote Services reporting. This also creates and configures the lockbox. The lockbox is also required for CloudIQ reporting. This is the best practice method for creating the lockbox.
NOTE: It is also possible to manually create the lockbox later, but the manual method involves security considerations.
If you select this option, the
Traps Receiver IP/Hostname field is displayed. Enter up to two (comma-separated) IP addresses or host names of the SNMP trap receiver servers.
Security options
Disable secure communication with the MDMs
Disable the need for secure communication mode between management clients and the MDM cluster members.
NOTE: Non-secure communication has security implications, and should be used with caution. For more information about this mode, see "Use SCLI in non-secure mode" in the
Configure and Customize
PowerFlex Guide.
Disable secure communication with the LIAs
Disable the need for secure communication mode between management clients and the LIAs.
NOTE: Non-secure communication has security implications, and should be used with caution. For more information about this mode, see "Use SCLI in non-secure mode" in the
Configure and Customize
PowerFlex Guide.
Disable authentication between internal components
Disable the need for authentication between SDSs and MDMs.
Use only the following trusted IP addresses for LIA (in addition to this gateway IP address)
Limit which
PowerFlex Gateway can communicate with the LIAs.
If you select this option, enter a comma-separated list of the IP addresses to trust (up to 32 IP addresses, including the IP address of this
PowerFlex Gateway). The
PowerFlex Gateway IP address is automatically added to the list and does not have to be explicitly mentioned. If the
PowerFlex Gateway uses multiple IP addresses, enter all the addresses.
You can use the
PowerFlex Installer to configure Syslog event reporting. You can also configure these features after installation, using the CLI. To configure Syslog reporting now, select
Configure the way Syslog events are sent, and enter the following parameters:
Syslog Server
The host name or IP address of the syslog server where the messages should be sent. Enter up to two server names or addresses, comma-separated.
Port
The port of the syslog server (default 1468)
Syslog Facility
The facility level (default: Local0)
Review the displayed information, by scrolling through the tables, and by hovering over the blue hyperlinks. To view the password that will be configured for a specific component, click
show.
If you have not done so yet, keep a record of all the passwords that you have assigned to the system components.
Scroll down to the
Storage Pool Configuration section of the table, select values for the following items. If the CSV file contained values in the
Storage Pool Configuration section, the values will already appear here. These values are mandatory.
The expected
Device Media Type
The
External Acceleration type (if used):
none—No devices are accelerated by a non-PowerFlex read or write cache
read—All devices are accelerated by a non-PowerFlex read cache
write—All devices are accelerated by a non-PowerFlex write cache
read_and_write—All devices are accelerated by both non-PowerFlex read and write cache
This input is required in order to prevent the generation of false alerts for media type mismatches. For example, if an HDD device is added which the SDS perceives as being too fast to fit the HDD criteria, alerts might be generated. External acceleration/caching is explained in the
Getting to Know Dell PowerFlex Guide.
Data Layout type (use with caution; data layout type cannot be changed after Storage Pool creation)
If Fine Granularity data layout is selected, select a
Fine Granularity ACCP (Acceleration Pool), and a
Compression Method
If Medium Granularity data layout is selected, the
Zero Padding option is available for selection. Use with caution, because the zero padding setting can only be changed in Storage Pools without any storage devices.
Replication Journal Capacity Percentage must be defined if SDRs are deployed in the system. For more information about calculating the appropriate value for your system, refer to the
Getting to Know Dell PowerFlex Guide.
NOTE: Fine Granularity can only be selected if the Storage Pool contains NVDIMMs and SSDs.
Click
