Configuring Server-Related Pools

This chapter includes the following sections:

Server Pool Configuration

Server Pools

A server pool contains a set of servers. These servers typically share the same characteristics. Those characteristics can be their location in the chassis, or an attribute such as server type, amount of memory, local storage, type of CPU, or local drive configuration. You can manually assign a server to a server pool, or use server pool policies and server pool policy qualifications to automate the assignment.

If your system implements multi-tenancy through organizations, you can designate one or more server pools to be used by a specific organization. For example, a pool that includes all servers with two CPUs could be assigned to the Marketing organization, while all servers with 64 GB memory could be assigned to the Finance organization.

A server pool can include servers from any chassis in the system. A given server can belong to multiple server pools.

Configuring a Server Pool

Procedure
  Command or Action Purpose
Step 1 UCS-A# scope org org-name  

Enters organization mode for the specified organization. To enter the root organization mode, type / as the org-name.

 
Step 2 UCS-A /org # create server-pool server-pool-name  

Creates a server pool with the specified name, and enters organization server pool mode.

 
Step 3 UCS-A /org/server-pool # create server chassis-num / slot-num  

Creates a server for the server pool.

Note   

A server pool can contain more than one server. To create multiple servers for the pool, you must enter multiple create server commands from organization server pool mode.
 
Step 4 UCS-A /org/server-pool # commit-buffer  

Commits the transaction to the system configuration.

 

The following example creates a server pool named ServPool2, creates two servers for the server pool, and commits the transaction:

UCS-A# scope org /
UCS-A /org # create server-pool ServPool2
UCS-A /org/server-pool* # create server 1/1
UCS-A /org/server-pool* # create server 1/4
UCS-A /org/server-pool* # commit-buffer
UCS-A /org/server-pool #

Deleting a Server Pool

Procedure
  Command or Action Purpose
Step 1 UCS-A# scope org org-name  

Enters organization mode for the specified organization. To enter the root organization mode, type / as the org-name.

 
Step 2 UCS-A /org # delete server-pool server-pool-name  

Deletes the specified server pool.

 
Step 3 UCS-A /org # commit-buffer  

Commits the transaction to the system configuration.

 

The following example deletes the server pool named ServPool2 and commits the transaction:

UCS-A# scope org /
UCS-A /org # delete server-pool ServPool2
UCS-A /org* # commit-buffer
UCS-A /org #

UUID Suffix Pool Configuration

UUID Suffix Pools

A UUID suffix pool is a collection of SMBIOS UUIDs that are available to be assigned to servers. The first number of digits that constitute the prefix of the UUID are fixed. The remaining digits, the UUID suffix, are variable. A UUID suffix pool ensures that these variable values are unique for each server associated with a service profile which uses that particular pool to avoid conflicts.

If you use UUID suffix pools in service profiles, you do not have to manually configure the UUID of the server associated with the service profile.

Configuring a UUID Suffix Pool

Procedure
  Command or Action Purpose
Step 1 UCS-A# scope org org-name  

Enters organization mode for the specified organization. To enter the root organization mode, type / as the org-name.

 
Step 2 UCS-A /org # create uuid-suffix-pool pool-name  

Creates a UUID suffix pool with the specified pool name and enters organization UUID suffix pool mode.

 
Step 3 UCS-A /org/uuid-suffix-pool # set descr description   (Optional)

Provides a description for the UUID suffix pool.

Note   

If your description includes spaces, special characters, or punctuation, you must begin and end your description with quotation marks. The quotation marks will not appear in the description field of any show command output.

 
Step 4 UCS-A /org/uuid-suffix-pool # create block first-uuid last-uuid  

Creates a block (range) of UUID suffixes, and enters organization UUID suffix pool block mode. You must specify the first and last UUID suffixes in the block using the form nnnn-nnnnnnnnnnnn, with the UUID suffixes separated by a space.

Note   

A UUID suffix pool can contain more than one UUID suffix block. To create multiple blocks, you must enter multiple create block commands from organization UUID suffix pool mode.

 
Step 5 UCS-A /org/uuid-suffix-pool/block # commit-buffer  

Commits the transaction to the system configuration.

 

The following example creates a UUID suffix pool named pool4, provides a description for the pool, specifies a block of UUID suffixes to be used for the pool, and commits the transaction: 

UCS-A# scope org /
UCS-A /org # create uuid-suffix-pool pool4
UCS-A /org/uuid-suffix-pool* # set descr "This is UUID suffix pool 4"
UCS-A /org/uuid-suffix-pool* # create block 1000-000000000001 1000-000000000010
UCS-A /org/uuid-suffix-pool/block* # commit-buffer
UCS-A /org/uuid-suffix-pool/block #

What to Do Next

Include the UUID suffix pool in a service profile and/or template.

Deleting a UUID Suffix Pool

Procedure
  Command or Action Purpose
Step 1 UCS-A# scope org org-name  

Enters organization mode for the specified organization. To enter the root organization mode, type / as the org-name.

 
Step 2 UCS-A /org # delete uuid-suffix-pool pool-name  

Deletes the specified UUID suffix pool.

 
Step 3 UCS-A /org # commit-buffer  

Commits the transaction to the system configuration.

 

The following example deletes the UUID suffix pool named pool4 and commits the transaction:

UCS-A# scope org /
UCS-A /org # delete uuid-suffix-pool pool4
UCS-A /org* # commit-buffer

Management IP Pool Configuration

Management IP Pool

The management IP pool is a collection of external IP addresses. Cisco UCS Manager reserves each block of IP addresses in the management IP pool for external access that terminates in the Cisco Integrated Management Controller (CIMC) on a server.

Cisco UCS Manager uses the IP addresses in a management IP pool for external access to a server through the following:


  • KVM console

  • Serial over LAN

  • IPMI

Configuring an IP Address Block for the Management IP Pool

Procedure
  Command or Action Purpose
Step 1 UCS-A# scope org /  

Enters root organization mode.

 
Step 2 UCS-A /org # scope ip-pool ext-mgmt  

Enters organization IP pool mode.

Note   

You cannot create (or delete) a management IP pool. You can only enter (scope to) the existing default pool.

 
Step 3 UCS-A /org/ip-pool # set descr description   (Optional)

Provides a description for the management IP pool. This description applies to all address blocks in the management IP pool.

Note   

If your description includes spaces, special characters, or punctuation, you must begin and end your description with quotation marks. The quotation marks will not appear in the description field of any show command output.

 
Step 4 UCS-A /org/ip-pool # create block first-ip-addr last-ip-addr gateway-ip-addr subnet-mask  

Creates a block (range) of IP addresses, and enters organization IP pool block mode. You must specify the first and last IP addresses in the address range, the gateway IP address, and subnet mask.

Note   

A IP pool can contain more than one IP address block. To create multiple IP address blocks, you must enter multiple create block commands from organization IP pool mode.

 
Step 5 UCS-A /org/ip-pool/block # commit-buffer  

Commits the transaction to the system configuration.

 

The following example configures an IP address block for the management IP pool and commits the transaction: 

UCS-A# scope org /
UCS-A /org # scope ip-pool ext-mgmt
UCS-A /org/ip-pool* # set descr "This is a management IP pool example."
UCS-A /org/ip-pool* # create block 192.168.100.1 192.168.100.200 192.168.100.10 255.255.255.0
UCS-A /org/ip-pool/block* # commit-buffer
UCS-A /org/ip-pool/block #

Deleting an IP Address Block from the Management IP Pool

Procedure
  Command or Action Purpose
Step 1 UCS-A# scope org org-name  

Enters organization mode for the specified organization. To enter the root organization mode, type / as the org-name.

 
Step 2 UCS-A /org # scope ip-pool ext-mgmt  

Enters the management IP pool.

 
Step 3 UCS-A /org/ip-pool # delete block first-ip-addr last-ip-addr  

Deletes the specified block (range) of IP addresses.

 
Step 4 UCS-A /org/ip-pool # commit-buffer  

Commits the transaction to the system configuration.

 

The following example configures an IP address block for the management IP pool and commits the transaction: 

UCS-A# scope org /
UCS-A /org # scope ip-pool ext-mgmt
UCS-A /org/ip-pool # delete block 192.168.100.1 192.168.100.200
UCS-A /org/ip-pool* # commit-buffer
UCS-A /org/ip-pool #
