• There are errors such as overlap in identity values with an existing pool.

• Syntax errors while entering the MAC, IQN, or network addresses.

Each identity pool provides information about the state of each identity in the pool. The states could be:

• Assigned

• Reserved

If the identity is assigned, the information about the assigned server and NIC Identier is displayed. If the identity is reserved, the

information about the assigned slot in the chassis is displayed.

You can create an identity pool with only the name and description and congure the details later.

NOTE: You can clear identities by disabling the I/O Identity Optimization option in iDRAC.

To create identity pools:

1 Click Conguration > Identity Pools.

The Identity Pools page is displayed with the list of available identity pools and their key attributes.

2 Click Create.

The Create Identity Pool wizard is displayed.

3 Enter a name and description for the identity pool and click Next.

The Ethernet tab is displayed.

4 Select Include Ethernet virtual MAC Addresses to enter the Starting MAC Address, select the Number of Virtual MAC Identities

you want, and click Next.

The MAC addresses can be in the following formats:

• AA:BB:CC:DD:EE:FF

• AA-BB-CC-DD-EE-FF

• AA.BB.CC.DD.EE.FF

You can choose to create the identity pools from iSCSI, FCoE, or FC.

The iSCSI tab is displayed.

5 Select the Include iSCSI MAC Addresses to enter the Starting MAC Address and select the Number of iSCSI MAC addresses or

IQN addresses you want.

6 Select the Congure iSCSI Initiator to enter the IQN Prex.

The pool of IQN addresses is generated automatically by appending the generated number to the prex in the format—<IQN

Prex>.<number>

7 Select the Enable iSCSI Initiator IP Pool to enter the IP Address Range, Gateway, Primary DNS Server, Secondary DNS Server,

and select the Subnet Mask.

The iSCSI Initiator IP settings are used only when the iSCSI is congured for booting, and when the iSCSI Initiator conguration

through DHCP is disabled. When iSCSI Initiator conguration through DHCP is enabled, all these values are obtained from a designated

DHCP server.

The IP Address Range and Subnet Mask elds are used to specify a pool of IP addresses that OME–Modular can assign to a device.

The device can use the IP in the iSCSI Initiator conguration. Unlike the MAC address pools, a count is not specied for the IP Address

Range. The pool of IP addresses can also be used to generate the initiator IP. OME–Modular supports the IPv4 format of IP addresses

range in the following formats:

• A.B.C.D - W.X.Y.Z

• A.B.C.D-E, A.B.C.

• A.B.C.D/E—This format is a Classless Inter-Domain Routing (CIDR) notation for IPv4.

A maximum of 64,000 IP addresses is allowed for a pool.

OME–Modular uses the Gateway, Primary DNS, and Secondary DNS server values while deploying a template instead of using the

values in the template.OME–Modular does not assign the Gateway, Primary DNS, and Secondary DNS server values from the IP
