When building new Linux boxes, I have to format several drives. I
normally log as Maint and do them one at a time. Is there a way to do
multiple drives simultaneously, or log to Maint sessions multiple times?
Any ideas as always are greatly appreciated.

We used a service machine for that that can dispatch work to other servers:
BUSERVER and BU1 through BUn as workers. It could work for you, but maybe
you'd need to change some REXX code (e.g. we used RACF, so we never had to
take care of passwords on LINK commands).

engines) but it doesn't show IFLs. Until 5.3, you couldn't really
tell if you were running on IFLs or CPs. If you're a Class G user,
the CP IND and Q PROC commands don't tell you either, even on 5.3 or
5.4. You need to use the

Check with your IBM C.E., they have the good stuff.

You can batch up the commands for ICKDSF (the guts of CPFMTXA) to do
multiple drives in series, but CMS is a single tasking OS. You can only do
them serially, or you need to use multiple userids. (note that it doesn¹t
have to be MAINT you can attach the disks to other userids from a
privileged
Another thought: If your disk subsystem supports snapshot, format one
³template² disk using CPFMTXA, attach it to a suitably privileged ID, attach
the new disk to your id, SNAPSHOT from the template to the new disk, then run
ICKDSF CPVOL FORMAT for just cylinder 0 giving the new label and CP
You can try using ICKDSF and write patterns of data on it to clear what
was there. This may not be good enough for some organizations but
is good enough for most. You can try something like the following:
TRKFMT UNIT(xxx) NVFY ERASEDATA CYLRANGE(,) CYCLES(x)

What would be the minimum acceptable value for CYCLES(x) to ensure data was not
retrievable?

TRKFMT is very slow process.
We have to wipe out our DR site at each test. Cycle for us is 3.
To do that I have developped something around DUPLICATE HiDRO cmd. The idea
is to TRKFMT volume A, B and C (3 cycles). Then we duplicate A to A', B to
B' and C to C' and again A to A, A to B and C
With a small change to my BUSERVER, ICKDSF TRKFMT commands could be
dispatched to 1 to 99 worker machines.

What is the vmsecure grant command that allows all authority for a userid?
I see in the authoriz config file on vmsecure's 191 disk the following entry...
grant *all to user1
I want to allow all for user2
What is the grant command format to accomplish this?
Thanks
We currently have z/VM 520 with RACF 1.10 and will shortly upgrade to
z/VM 540 with the RACF feature for 540.
We want to synchronize new passwords across a number of systems.
I have looked thru the manual and it's not obvious to me if there is an
exit available that will get called AFTER RACF
From an authorized UserID (for example VMRMAINT), issue:
-- VMSECURE ADMIN CONFIG
Select option 3, Authorizations ...
Add (or duplicate) the GRANT record you said you found:
-- GRANT *ALL TO USER1
Change USER1 to the name of the UserID you want to have God-like
authority to issue any

I've been part of a team writing a redbook on the subject last
September/October. You need z/VM 5.4 with RACF and LDAP (included with
z/VM) and Tivoli IBM Tivoli Directory Integrator (ITDI, included in some

On Mac OS X's Disk Utility there are Secure Erase Options and under a 7-Pass
Erase it says that it meets the US Department of Defense 5220-22 M standard
for securely erasing magnetic media. There is also a 35-Pass Erase option
with no standard attached to it. I always wondered why is it there...
