LPAR freezes after switching of storage (lpar is mirrored)
Hi all,
I have the following configuration
2 ds3524 storage disk systems located over 2 locations
2 P720 server located over 2 locations
DS3524 are connected to san switch.
Each vio server has 1 fc adapter attached to a san switch.
per p720 server 2 virtual io servers. Vio 1 has 1 lun from 1 ds3524, Vio 2 has 1 lun from the other ds3524
On the lpar we use LVM mirroring.
The problem:
When we halt 1 DS3524 the lpar freezes for about 30 seconds and then is again available.
Is this normal behaviour? When i shutdown 1 vio server , everything on the lpar is ok , no freeze.
Any ideas ?
thx MarkieMark
