Bonjour,

I guess that yes you still can use sasmgr with HP-UX 11.31.

man sasmgr, for "sasmgr replace_tgt -D device_file -q old_dev=lun_dsf -q new_tgt_hwpath=new_hw_path" says :

"The lun_dsf must be the legacy device file and the new_hw_path must be the legacy hardware path. This command does not allow a persistent device file or the new style hardware path to be specified with the old_dev and new_tgt_hwpath qualifiers."

Also from same manpage, you can use "io_redirect_dsf"

I must apologize :-(

Reading documentation at http://docs.hp.com/en/J6369-90071/J6369-90071.pdf, page 65 and later, I guess that sasmgr will only do the work on legacy dsf. If you use persistent dsf, you should also consider using "io_redirect_dsf"

also:http://www13.itrc.hp.com/service/cki/docDisplay.do?docLocale=en&docId=emr_na-c01037901-4 :
io_redirect_dsf is a new command introduced with HP-UX 11.31. It redirects the
persistent DSF from one device to a different device. This is equivalent of the command sasmgr replace_tgt.

Re: scsimgr or sasmgr

It depends!

For hardware raids managed by the default built-in controller you just swap the disk and check with sasmgr.

For "plain" disks see

Hope this helps!
