Server discovery

You can do out-of-band discovery of unassigned Dell servers and import information about Dell servers into the appliance.

You can discover Hyper-V hosts and modular Hyper-V hosts along with unassigned servers. After discovery, the servers are added

to respective predefined update groups. For more information on classification of server groups, see

Server management .

Server discovery notes:

• When you discover a Dell PowerEdge server with an operating system and already present in SCCM or SCVMM, then the

server is listed as a host server and marked as compliant or non-compliant.

– A host server is compliant when it contains minimum versions of LC firmware, iDRAC, and BIOS that are required to work

with the appliance.

– If the host is a modular server, then the service tag of the chassis containing the server is also displayed.

– If the host is part of a cluster, then the Fully Qualified Domain Name (FQDN) of the cluster is displayed.

• When you discover a Dell PowerEdge server that is not listed in SCCM or SCVMM, then the server is listed as an unassigned

server and marked as compliant or noncompliant based on their versions of LC firmware, iDRAC, and BIOS.

• If you provide incorrect credential details, then based on the iDRAC version, the following resolutions are available:

– While discovering a 12th generation Dell PowerEdge server with iDRAC version 2.10.10.10 and later, if incorrect details are

provided in the credential profile, the server discovery fails, with the following behavior:

* For first attempt, server IP address is not blocked.

* For second attempt, server IP address is blocked for 30 seconds.

* For third and subsequent attempts, server IP address is blocked for 60 seconds.

You can reattempt server discovery with correct credential profile details once the IP address is unblocked.

– While discovering an 11th or 12th generation PowerEdge server with iDRAC versions prior to 2.10.10.10, if server discovery

attempts fail due to incorrect credential profile details, then rediscover the server with the correct credential profile details.

– For iDRAC versions prior to 2.10.10.10, blocking of IP addresses is configurable. For more information, see iDRAC

documentation at Dell.com/idracmanuals. Based on your requirement, you can also disable blocking of IP addresses. And

you can also check if the iDRAC.IPBlocking.BlockEnable feature is enabled in iDRAC.

– If the default iDRAC credential profile is changed after a server is discovered and added in the appliance, then no activity can

be performed on the server. To work with the server, rediscover the server with the new credential profile.

You can also discover Dell servers using the following options:

• Auto discovery of servers.

• Manual discovery based on IP addresses.

System requirements for managed systems

Managed systems are the systems that are managed using the appliance. For appliance to discover managed systems, following are

the system requirements:

• For the 11th, 12th, and 13th generation of Dell PowerEdge servers, the appliance supports modular and monolithic server models.

• For source configuration and destination configuration, use same type of disks — only Solid-state Drive (SSD), SAS or only

Serial ATA (SATA) drives.
