Hello,
We have a TRU64 host with few domains created. It has the external disk array as well connected via SCSI cables.
one of the admins , accidently removed the scsi connectors from the external disk and that made one of the domain
as inaccessible. Domain Panic. The domain has some data files in it so the server is still up.
Now the question is , in order to bring the system to the previous stage, if we shutdown the host and connected
the cables as before and then start up the host, will the system take up??
I am thinking of hash out the domain entry from /etc/fstab and then bring the system up and then try to
mount the domains/shares one by one.
Kindly suggest at the earliest.
Thanx,
admin

You can try to connect the connector and scan the disks again and see if they are availabel.
If its only related to SCSi connector, i don think you need to hash out /etc/fstab.
But its good idea.

Thanks Kapil. Problem is I can see all the disks in scu show. Still I did scan. Shows 17 disks.
But the problem is , when I try to access any share I get,
# cd /opt
ksh[6]: /opt: permission denied
So looks like something we need to do to remap the domain.
We use LSM.
Thanx. |

Are the devices showing up with the same names as before? Or has the scsi ids changed? If the names are same, then you can try showfdmn directly. |

Yes the SCSI ids are same as before. I cross checked with scu show edt. And we have aleady used showfdmn in /etc/fdmns/
Getting following error for the said domain,
# showfdmn source_domain
showfdmn: unable to get info for domain 'source_domain'
showfdmn: error = I/O error

Like said before, we have below dg's in it.
# voldg list
NAME STATE ID
rootdg enabled 966101943.1025.bwgb550.vt.siemens.de
sourcedg disabled 1007210557.3627.bwgb550.vt.siemens.de
dokudg enabled 940102215.1973.bwgb550.vt.siemens.de
toolsdg enabled 944403128.1335.bwgb550.vt.siemens.de
If I do voldg disable command , will it affect any of the working dgs...i mean it should not ...as it also has rootdg in it.
So concerned.
If disable/enable do not work. Can you please give me the further steps to import/deport |

from your post i think your sourcedg is affected and if you do anything on it other DG would not be impacted.
i would suggest
export dg
voldctl disable/enable
import dg
Should work!!
Only touch affected dg nothing would happen :)

Thank you. To start with , I just cross checked the first command in MAN page.
#voldg export sourcedg [use -f if not happening]
But unfortunately could not find the export option against voldg command.
There are only import/deport options.
Or am I missing something here. Please let me know.
By the way , ours is a TRU64 V4.0D system. |

Ohhhh,
Are we sure this time,
#voldg deport sourcedg [user -f is not happening]
#voldctl disable
#voldctl enable
#voldg import sourcedg
By the way I could not find -f option for deport. |

Commands are present as I can see in MAN.
Will reboot fix this problem? What do you think? |

If command are there i don think there is any harm in running,
At least you would save a reboot , else I suppose reboot would definetly solve the issue.
BUT
before rebooting try to run commands.

Ok hope so.
Anyways first command said,
# voldg deport sourcedg
voldg: Disk group sourcedg: Some volumes in the disk group are in use.
Is it becauze few of the filesystems are still mounted and could not be unmounted from the sourcedg? There are getting Device busy error.
For you information,
here is the o/p of my working sourcedg taken long back,
volprint -g sourcegdg

Should I try this,
volume -g sourcedg stopall
They say "To deport a disk group: If applicable, stop the volumes" |
