ACLs on Tape Drives with TMSCP=1

[Vinit Adya]

I am running VMS 7.2-1 on a 2 node Memory Channel alpha cluster. I enabled TMSCP so as to serve the TZ89s attached to PCI SCSI on one of the systems. Since i enabled it i realized i can no longer put ACLs on the device. Dose anyone have any clue as to what is happening?

What command are you using and what error do you get?

double check the location of VMS$OBJECTS.DAT in SYS$SYSTEM:. Make sure that the nodes in your cluster are sharing only one copy.

Also, according to documentation, it is suggested that the logical name VMS$OBJECTS, if used, be defined in SYSECURITY.COM to survive reboots. It should point to the file that all the nodes share.

Try issuing your command(s) for setting up the ACl on all nodes to see if that makes a difference.

refer to the sections "Setting Up Profiles for New Devices", "Modifying a Security Profile" and " Specifying an Object's Class" in the OPENVMS GUIDE TO SYSTEM SECURITY.

Let me clarify further. With TMSCP set to 0 i can set ACLs; The tape drives in questionare seen by both the cluster nodes. Shared through a HSZ50. When i turn TMSP=1 ACLs stop working.

Addl info: I want to turn on TMSCP to server 2 other tape drives which are locally attached. These locally attached drives behave normally (can set ACLs) irrespective of the state of TMSCP.

Lokesh,

The command I use is:
$ set acl/obj=dev/acl=(id=*,ac=w+R+E+D+C) $2$MKA0:
There is no error message. Just the ACL is not set on the drive.

As of now, i have switched off TMSCP and the drive looks like: (ACL is present)

Magtape $2$MKA0: (SIALP7), device type TZ88, is online, file-oriented device,
error logging is enabled, controller supports compaction (compaction
disabled), device supports fastskip.

Hi Vinit,

Looks strange. Have you raised this issue to HP support ? When I will get chance, I will try to simulate the problem.

Best regards,
Lokesh

P.S. ( you were in CMC limited, Delhi (india) . Am I right ?? )
