Flex Appliance 2.1.1 new features, enhancements,

and changes

The following list describes the new features, enhancements, and changes in the

Flex Appliance 2.1.1 update:

■ To modernize our terminology, Veritas has begun to replace certain outdated

terms with more current terms. Flex Appliance now uses "primary server" instead

of "master server."

Note: As Veritas continues to update its terminology, the deprecated terms and

the new terms may be used interchangeably.

■ LDAP users are now supported on the Flex Appliance Console.

See “Managing Flex Appliance Console users and tenants” on page 52.

■ You can now use smart cards or certificates for user validation with a remote

user domain.

16Release notes

Flex Appliance 2.1.1 new features, enhancements, and changes

■ During an instance upgrade, an issue can occur that causes the following error

to display in the Activity Monitor:

"Create snapshot failed with error exec: Stdout already set"

This issue is fixed in the 2.1.1 update. If you encounter this issue in version 2.1,

retry the upgrade. If the problem persists, restart all nodes on the appliance and

try again.

■ When you create an instance or configure a proxy server for Call Home, an

issue can occur with the file uploads if you upload a file with incorrect data. If

you edit the file to correct the issue and then attempt to upload it again, the

upload still fails.

This issue is fixed in the 2.1.1 update. If you encounter this issue in version 2.1,

exit the operation and start it again.

■ The set alerts hardware-threshold command was added this release to

set threshold values for alerts. However, alerts are not currently sent for the

metrics that can be set with this command.

■ The support data-collect command may show the following error:

"*** Error in `qaucli': double free or corruption"

This error can be safely disregarded. The command still generates a DataCollect

package.

■ During an instance upgrade on a Veritas 5150 Appliance, the upgrade precheck

may fail with the following error message:

"V-492-101-102: Not enough space; request size of 256000 MB is greater than

remaining space of <available space> MB. The log volume and the internal data

volumes are included in space calculations."

If you encounter this issue, resize one or more of your application instances to

make sure that there is 250 GB of available storage space. Then retry the

upgrade.

■ During a firmware upgrade, an issue can occur with the storage shelf controller

that causes an upgrade failure message to appear. If you see a failure message,

it may have appeared in error, and the upgrade may still have worked. Run the

following command to confirm the firmware version:

show hardware-health primaryshelf component=controller

■ If you upgrade to version 2.1 and then roll back, an issue can occur that causes

the Flex Appliance Console to be unable to load. If you encounter this issue,

restart all appliance nodes and then try again to access the console.

Warning: If you have a multi-node appliance, do not restart both nodes at the

same time.

18Release notes

Operational notes

■ For this release, while an update is in progress, do not perform any other

operations in the Flex Appliance Shell or the Flex Appliance Console.

■ If you change the BIOS date and time on a Veritas 5250 Appliance after initial

configuration, you can no longer access the Flex Appliance Console.

This issue is fixed in the 2.1.1 update. If you encounter this issue in version 2.1,

change the BIOS date and time back to what it was before.

■ When you create a bond, do not give it a bond name that is all numbers. If you

do so, you can no longer create any additional bonds on the appliance.

If you were not aware of this limitation and have already created a bond name

that is all numbers, contact Technical Support for assistance. Ask your

representative to reference article 100050464.

■ Accelerator backups on Flex Appliance application instances fail if there is not

enough space for the logs. For example, the logs for NDMP backups could

require up to a Terabyte of storage space.

On a primary server instance, the logs are stored in the same location as the

NetBackup catalogs. To resolve this issue on a primary server instance, resize

the NetBackup catalog and make sure to allocate enough storage for the

Accelerator logs as well.

On a media server instance, the logs are stored in the /mnt/nblogs directory,

which has a default size of 250 GB. This directory cannot currently be resized

through the Flex Appliance Console.

On version 2.1.1, you can resize the directory with the PUT

/instances/<instance-id>/volumes API. See the Flex Management Server

API documentation on Veritas SORT for details.

If you are on version 2.1, contact Veritas Support and ask your representative

to reference article 100049971 to resize the directory.

■ Due to an underlying performance issue, the monitoring and alerting feature for

the ROC Temperature (RAID on Chip for RAID Adapters) is disabled in this

release for the Veritas 5250 Appliance. This feature will be reinstated and

available for 5250 models in a future software release.

■ When you install application add-ons on an instance, the Flex Appliance Console

lets you select different versions of the same OST plug-in. However, this

configuration is not supported, and if you select more than one version of the

same plug-in, the Install add-ons page shows duplicate entries. Only install

one version of each OST plug-in on an instance. If you need to change the

version of an OST plug-in that is already installed, first uninstall it, and then

install the new version.

■ If the host0 or host1 port is not connected to the appliance node during initial

configuration, the following error message appears that does not provide

complete information:

19Release notes

Operational notes

“Network card for <interface name> is missing. Make sure that all network

interfaces are connected to the appliance.”

If you encounter this message, verify that all ports are connected according to

the initial configuration guidelines. See “Initial configuration guidelines and

checklist” on page 23. Then restart the node to continue the configuration.

■ When you create a new application instance, the Application instances section

of the System topology page may show the instance status as Partially Deleted

while the creation is in progress. The Partially Deleted status displays in error

and can be safely ignored. You can track the instance creation progress from

the Activity Monitor, and the instance status changes to Online when the instance

creation has completed successfully.

■ If you have a tenant whose name or location contains special characters when

you upgrade to version 2.1, tenant operations fail after the upgrade. To resolve

this issue, edit the tenant name and location so that they do not have special

characters.

■ The following error message may display in the Flex Appliance Shell during an

upgrade or a factory reset:

dracut:Failed to install module bnx2

This message displays in error and can be safely disregarded.

■ If you have a multi-node appliance and one of the nodes is turned off for any

reason, do not restart the other node until they are both online. If a node is

restarted while the other node is off, the Flex Appliance Console fails to load.

If you encounter this scenario, contact Veritas Technical Support and ask your

representative to reference articles 100046118 and 100051413.

■ When you create an instance, if you enter the IP address before you select a

network interface, the IP address field displays the following error message:

“IP address does not belong to the selected network’s subnet.”

This message still displays after you select the network interface that corresponds

to the IP address. To clear the message, click inside the IP address field and

then click or tab outside of it.

■ After some operations in the Flex Appliance Shell, an “Operation successfully”

message may display even if a failure occurred. Read all of the messages that

display at the end of each task to make sure that no further action is required.
