1-1Cisco UCS Invicta Super User Guide

OL-25761-DRAFT

1Super User Support Menu

This guide includes information about the Cisco Unified Computing System (Cisco UCS) Invicta Scaling System for both performance and data reduction silicon storage systems. Information applies to both types of systems unless otherwise noted.

• Console Monitor, page 1-2

• Current Sessions, page 1-3

• Kernel Messages, page 1-3

• System Log, page 1-4

• Acceleration Stats, page 1-4

• RAID Stats, page 1-7

• Interface Stats, page 1-7

• Support, page 1-7

Prerequisite Tasks • You must be logged in as a Super User to perform Super User tasks.

• The Super User password must be changed after initial login.

• Sign in again with the changed password.

The following is a list of Super User features:


Chapter 1 Super User Support MenuConsole Monitor

Figure 1-1 Super User Support Menu

• View Console Monitor

• View Support Menu and Functions:

– Current Sessions

– Kernel Messages

– System Log

– Acceleration Stats

– RAID Stats

– Interface Stats

This section explains the Super User Support Menu. The figures that accompany the content are intended as examples.

Note INVICTA Scaling System is used in the Super User figure samples, but the Invicta C3124SA Appliance Support menu items will look similar, except where noted.

Console MonitorThe console monitor provides a view of the system log. It appears on the bottom of every GUI window in its "hide" state and can be dragged as a standalone window. The console is only visible to those that are logged in as superuser monitor.

Click the "show/hide" icon on the right-hand side of the Console Monitor title bar to view/close the window.


Chapter 1 Super User Support MenuCurrent Sessions

Figure 1-2

Current SessionsThe Current Sessions window lists the current iSCSI and Fibre Channel initiator sessions.

To view current sessions:

Step 1 Select Support > Current Sessions.

The Current Sessions window appears.

Step 2 Click a session to view its attributes

Note “qlaXX" denotes a Fibre Channel target or driver.

Kernel MessagesKernel Messages displays log messages that indicate the way in which the kernel is processing requests,

for example, logins with an identifier and timestamp,( e.g., 111069.872945).

To view kernel messages, select Support > Kernel Messages.

The System Log window appears.


Chapter 1 Super User Support MenuSystem Log

System Log

Note If a notice appears stating that the system log is too large to display, contact Cisco Technical Support for assistance viewing this log.

To view system log details, select Support > System Log.

The System Log window appears.

Acceleration StatsFigure 1-3 Acceleration Stats Window

To access the menu:

Step 1 Select Support > Acceleration Stats.

The Acceleration Stats window appears.

Step 2 Select an SSN from the drop-down list to view its associated Acceleration statistics. These include:

• Configuration

• IO

• Wear

• GC stats


Chapter 1 Super User Support MenuAcceleration Stats

The Acceleration Stats window also provides array management functionality. Table 1-1 lists and explains these functions.

Setting the Garbage ThresholdGarbage Collection (GC) starts eviction and frees write blocks when the {gc_threshold%} of write blocks are free. To set the GC, do the following:

Table 1-1 Acceleration Stats Descriptions

Function Name Description Notes

Garbage Collection Threshold (GC)

GC starts eviction and frees write blocks when the {gc_threshold%} of write blocks are free.

The default threshold value is 30%.

If GC already triggered, the GUI will pop up a message.

Date Age Timer Updates the maximum data_age of each write_block. Data age is calculated from the time the data is first written after this interval, the complete data in the write_block is flushed.

Its value is in terms of milliseconds with a default value of 500 milliseconds.

GC Trigger Initiates Initiates Garbage Collection (GC) outside of the threshold parameter set by the Threshold GC function.

Release Reserve/Recreate Reserve

For deduplication nodes:

• For Release 5.0.1.2a and later, if a disk-full scenario occurs, the Release Reserve function releases 10GB of the Volume Group so that the writing and deleting data can continue.

• Recreate Reserve reinstates the 10GB Reserve LV.

Reserve LV can only be recreated if the physical space availability is greater than 50 GB. Before attempting to recreate a Reserve LV, check the available space on the Volume Group using the GUI (see Release Reserve/Recreate Reserve later in this section).

• A 10 GB Reserve LV is factory set.

• The default button on a deduplication node is Release Reserve.

• Once the reserve is released, the Recreate Reserve button is displayed in its place.

Note If the Reserve LV was released prior to the upgrade to OS v5.0.1.3, then the Reserve LV will NOT be automatically created by the WSP package upon install. In this case, create the Reserve LV again manually after the WSP install by logging in as Super User.


Chapter 1 Super User Support MenuAcceleration Stats



Step 2 (For SSR only) From the drop-down list, at the top of the window, select the SSN for which the GC is be set. SSN1 is the default.

Step 3 Click GC Threshold.

The Set GC Threshold window appears.

Step 4 Select the GC Threshold percentage from the drop-down list.

Recreate Reserve/Release Reserve• A 10 GB Reserve LV is factory set.

• The default button on the deduplication node is Release Reserve.

• Once the reserve is released, the Recreate Reserve button is displayed in its place.

Note If the Reserve logical volume (LV) was released prior to the upgrade to OS v5.0.1.3, then the Reserve LV will NOT be automatically created by the WSP package upon install. In this case, create the Reserve LV again manually after the WSP install by logging in as Super User.

Reserve LV can only be recreated if the physical space availability is greater than 50 GB. Before attempting to recreate a Reserve LV, using the GUI, check the available space on the Volume Group by doing the following:

Step 1 Select SSR Configuration > VG/Node Settings.

The VG/Node Settings window appears.

Step 2 Right-click the deduplication Volume Group where the Reserve LV is to be created.

Step 3 Select Physical Space from the menu.

The Logical Space vs. Physical Space graph appears.

To recreate or release a Reserve LV:



Step 2 (For SSR only) From the drop-down list, at the top of the window, select the deduplication SSN for which the Reserve LV is being created.

Step 3 Click Release Reserve/Recreate Reserve.

Step 4 If recreating a Reserve LV, a 10 GB Reserve LV is created by default.
