Hi everybody
I had last Friday a very strange problem with my StorageWorks.
My HSG80 (Software V86F-4) configuration look like that:
stripeset DVGRPSM4
MIRR_16 (DISK10300,DISK20300)
MIRR_15 (DISK30300,DISK40300)
MIRR_14 (DISK50300, DISK60300)
Host_1 18.2GB (Partition on stripeset DVGRPSM4)
Host_2 18.2GB (Partition on stripeset DVGRPSM4)
Host_3 18.2GB (Partition on stripeset DVGRPSM4)
Host_4 18.2GB (Partition on stripeset DVGRPSM4)
Host_5 18.2GB (Partition on stripeset DVGRPSM4)
Host_6 18.2GB (Partition on stripeset DVGRPSM4)
The root_domain, usr_domain, and var_domain are on Storageworks and the
data_domain are on Hitachi disk subsystem.
I have naturally other stripsets but I didn't notice any problem with them.
I modified the /etc/ddr.dbase (see below) file on the Host_2 (Tru64 5.1A) to
have the best configuration for my Hitachi 9980V disk subsystem. After I
changed this file I made a ddr_config -c to activate this change.
I made an hwmgr -scan scsi on the Host_2 to see my new devices and this
command crashed the Host_1 (Tru64 5.1), Host_3 (Tru64 5.1) and Host_4 (Tru64
5.1). It was impossible to restart Host_1, Host_3 and Host_4 (wwidmgr: not
connected devices) I had to boot first with the CD-ROM and only after it was
possible to boot normally. After that I restarted the Host_2 and during the
boot process 4 Systems crashed. I remove my modifications in the
/etc/ddr.dbase file and everything work fine.
I have 3 questions:
1) Are my modifications in the /etc/ddr.dbase file so "dangerous"?
2) It's really possible inside a StorageWorks from one system to crash
other systems?
3) Where is exactly the problem Host_2 or HSG80 (StorageWorks)?
Any hints are really welcome.
Best regards,
Stephane
