OpenVMS SAN Disk Configuring Boot Path

My customer has two SuperDome OpenVMS v8.4. The boot disks are in SAN Storage Disk. I have configured the boot paths using:

 

vms_bcfg boot fibre 1

reconnect -r

map -r -Fs

or

setting EFIFCScanLevel policy to 1.

 

All ways scans the entire SAN (zone) for all available device LUNs. But when the server is reset some path settings are lost.

I think It's necessary to save these paths scaned on NVRAM but I don't know how I can do this.

thanks in advance

Re: OpenVMS SAN Disk Configuring Boot Path

After you scan the SAN, set the boot alias.  See if FC SAN Tips: OpenVMS Fibre Channel SAN Disk Device Configuration gets you where you need, or (since this is VMS) you can also skim the installation manuals.  (There are links to a couple of the relevant manuals and the target tools you'll be using in that article, too.)

Re: OpenVMS SAN Disk Configuring Boot Path

Hi Hoff

I have used your articles to do these tasks. Many thanks for your knowledge database.

 

I define the boot alias using vms_bcfg or @boot_options and then reset the server, after this the file systems (eg, fs3:, fs5:) disappear.

 

There are two controller (FGA and FGD), two disks (dga1 and dga101). two paths to each disk (DGA1 WWN = 2E84 and 2E94,

DGA101 WWN = 4184 and 4194). Paths to DGA1 disappear after reset).

 

I,m sending attached console display.

thanks & regards

Carla

Hi Carla,

     Just one observation from reading your attachment.    It doesnt look like you "wrote" your changes when you left drvcfg.

 

After you make your change to efiscanlevel, you must select "write" before leaving the utility, or your changes will be lost.

Carla,

      One other comment,   

 

If you have multiple HBA's, you must repeat the process of setting the efiscanlevel, for each HBA.
