sorry that didnt help. i know that i have to specify the nic:

/admin1-> racadm get nic.nicconfig.1
[Key=NIC.Integrated.1-1-1#nicconfig]
LegacyBootProto=PXE
#LnkSpeed=AutoNeg
#NumberVFAdvertised=32
VLanId=642
WakeOnLan=Disabled
/admin1-> racadm set nic.nicconfig.1.bootretrycnt 1
ERROR: RAC1019: The specified object is not supported for the current system
       configuration.
       Verify the object dependency using "racadm help
       class>. . ", and retry the operation. For example,
       "racadm help NIC.vndrConfigPage.1.VirtWWPN".
/admin1->

also i have tried with several firmware-versions across my customers: versions 2.15, 3.00, 3.30, 3.60, 4.00. except for v4.00 the setting is described in the correspondent racadm-cli-guide but not available for racadm

Bewe2005,

It will depend on the nic you are using.

If nic 1 the command is

racadm set NIC.NICConfig.1.bootretrycnt -1 in order to set it to 1.

If nic 2 it would be

racadm set NIC.NICConfig.2.bootretrycnt -1 to set it to 1. 

Let me know if this helps.

no that didnt help also:

bootretry 1

bootretry -1

bootretry - 1

calling the help function gives me (FW-Version 4.00):

racadm>>help nic.nicconfig.bootretrycnt
Dependency -- None
BootRetryCnt -- Specify the number of retries to attempt in case of boot failure.
Usage -- NoRetry - 0;1Retry - 1; 2Retries - 2;3Retries - 3;4Retries - 4; 5Retries - 5;6Retries- 6; IndefiniteRetries, Default - NoRetry
Required License -- RACADM
Dependency -- None

racadm>>

Does it work if you put a hypen at bootretrycnt - 1, so

racadm set nic.nicconfig.1.bootretrycnt - 1

finally found the solution: it depends of the nic vendor which options are available.

intel nics do not have the bootretrycnt-parameter, but broadcom has
