Scripting ISCSI

[virtech]

I'm trying to script software iscsi, however when I use the following command : vmkiscsi-tool vmhba40 -D -a 10.42.10.131:3260

I receive the following error:

Found no Phba's

Could not find valid OIDs for adapter vmhba40

It would appear from the error the command is assuming I have an HBA in my server ?

[Leo_Smith]

vmhba40 is the software iscsi adapter that vmware uses go into configuration and storage adapters in VI to see it

[virtech]

Yep thats what Im trying to configure software iscsi

[BUGCHK]

I've done some browsing and found the following command style:

vmkiscsi-tool -D -a 10.42.10.131 vmhba40

Did you already enable the software adapter with:

esxcfg-swiscsi –e

?

[virtech]

Yeah I have tired that command style as well, same error message.

Yes esxcfg-swiscsi –e has been run first.

There doesn't appear to be much documentation on this anywhere?

hi,

i got it working in my scripted installation with these commands

\- make sure you have a working vmkernel...

1) open the firewall

esxcfg-firewall --enableService swISCSIClient

2) enable swiscsi

esxcfg-swiscsi -e

3)set an iscsi-name (with your specific iqn name)

vimsh -n -e "hostsvc/storage/iscsi_set_name vmhba40 iqn.2000-04.com.qlogic:esx01.domain.com"

4) if you use chap then enable it like this...

vimsh -n -e "hostsvc/storage/iscsi_enable_chap vmhba40 login_chap chap_password"

5) enter your targets

vmkiscsi-tool vmhba40 -D -a 172.22.4.18:3260

vmkiscsi-tool vmhba40 -D -a 172.22.4.11:3260

6) do a rescan

esxcfg-swiscsi -s

7) another rescan (don't know if this have to..)

esxcfg-rescan vmhba40

😎 enable all changes in the viclient

service mgmt-vmware restart

(and last.. if it's possible reboot.. this should enable everything and get it working...)

hope this helps..
