disk, mirror and cluster Information

[Carme Torca]

Hi,

I would like to know who could I know the configuration of a system, and if it's in cluster or no, and if it's in mirror or no.

I have this structure:

#root 131072 68261 57824 55% /cluster/members/member1/boot_partition

sapdir02_domain#D02 2097152 662917 1427448 32% /usr/sap/SCP/D02


but I don't know if this filesystem are in mirror, or not... And if they are in cluster or not.

Thanks!,
Carmen.

To show the devices which build a file domain use

#showfdmn usr_domain

if the output is like tho following
----
showfdmn usr_domain

Id Date Created LogPgs Domain Name
35085b8e.000635d0 Thu Mar 12 23:02:54 1998 512 usr_domain

Vol 512-Blks Free % Used Cmode Rblks Wblks Vol Name
1L 5735160 1445392 75% on 256 256 /dev/rz0g
---
the that domain is on a single hd
while if the output is like
---
showfdmn usr_domain

Id Date Created LogPgs Version Domain Name
3c8c9134.0005cee0 Mon Mar 11 12:12:52 2002 512 4 usr_domain

Vol 512-Blks Free % Used Cmode Rblks Wblks Vol Name
1L 5770928 674768 88% on 65536 65536 /dev/vol/rootdg/vol-dsk0g
---

with a meta-device like /dev/vol/rootdg/vol-dsk0g
then it is a sort of raid device.

root can run
#dxlsm

to have a gui to monitor all disks.

Peace, R.

Hi Carmen,

use
clu_get_info -full
to check out, whether the host is in a cluster.
volprint -Aht
whether you use lsm mirroring.
Please tell us more about hardware configuration and post showfdmn -k of your file sets.

greetings,

Michael

Hi,

I have this:

#showfdmn -k root1_domain

Id Date Created LogPgs Version Domain Name
3dfb004d.010eb73f Sat Dec 14 10:56:29 2002 512 4 root1_domain

Vol 1K-Blks Free % Used Cmode Rblks Wblks Vol Name
1L 131072 57824 56% on 256 256 /dev/disk/dsk76a

it would say that is not in mirror, isn't it?

And about Cluster:

#clu_get_info -full
Cluster information for cluster cluster1

Number of members configured in this cluster = 2
memberid for this member = 1
Cluster incarnation = 0xa028
Cluster expected votes = 3
Current votes = 3
Votes required for quorum = 2
Quorum disk = dsk81h
Quorum disk votes = 1

Information on each cluster member

Cluster memberid = 2
Hostname = chang2
Cluster interconnect IP name = chang2-mc0
Cluster interconnect IP address = 10.0.0.2
Member state = UP
Member base O/S version = Compaq Tru64 UNIX V5.1 (Rev. 732)
Member cluster version = TruCluster Server V5.1 (Rev. 389)
Member running version = INSTALLED
Member name = chang2
Member votes = 1
csid = 0x10002

Cluster memberid = 1
Hostname = chang1
Cluster interconnect IP name = chang1-mc0
Cluster interconnect IP address = 10.0.0.1
Member state = UP
Member base O/S version = Compaq Tru64 UNIX V5.1 (Rev. 732)
Member cluster version = TruCluster Server V5.1 (Rev. 389)
Member running version = INSTALLED
Member name = chang1
Member votes = 1
csid = 0x10001

Could I know what filesystems are in this cluster?, Is there any configuration cluster file?

Thanks!!
Carmen.

[Roberto Polli]

1) the first is ok: not mirror
2) you miss the volprint output.

cluster fs should be in /cluster/member/ but M. will say better

Hi,

The volprint, says these:

#volprint -Adt
lsm:volprint: ERROR: IPC failure: Configuration daemon is not accessible


Thanks!,
Carmen.

[Roberto Polli]

no soft mirrors.

#dxlsm
must show the same.

Maybe you have hw mirror. To manage you need the hp-gives software.

Which controller do you have?
Peace, R.

[Carme Torca]

Hi Roberto,

You are a great help to me!!!
How I could know the driver??, what's the instrucction?

Thanks!

[Michael Schulte zur Sur]

Hi Carmen,

so you have a 2 member cluster, no lsm mirroring.

If you can, shutdown machine and prompt
show dev
show config
If not, post
/dev/rdisk/dsk76a

thanks,

Michael

[Roberto Polli]

Michael,
maybe no need to boot: I remember that for setting NIC I used consvar.

To get info use
/sbin/consvar -l dev
/sbin/consvar -l config
man consvar


PS.Michael about my last posting about advfs, i didn't came to a solution. Do you know something else?
