Hi Friends,

config disk c48t7d7 copy 1 len=727 disabled
log disk c48t0d0 copy 1 len=110
log disk c48t0d1 copy 1 len=110 disabled
log disk c48t0d2 copy 1 len=110 disabled

log disk c48t0d4 copy 1 len=110 disabled
log disk c48t0d5 copy 1 len=110 disabled
log disk c48t0d6 copy 1 len=110 disabled
log disk c48t0d7 copy 1 len=110 disabled
log disk c48t1d0 copy 1 len=110
log disk c48t1d1 copy 1 len=110 disabled


Now can anybody tell me what is the meaning of config disk online and config disable . Also log disk disable and vise versa .

Hi,

The lines you are referring to show the state of the disk group configuration records for each disk in the disk group. As long as there is at least 1 good copy of this the disk group can be imported. As you can see from your output 2 disks in your disk group have clean config records.
If you want veritas to replicate the config records to other disks in the disk group (for greater redundancy) you can use the following command:

vxedit -g sb2dg01 set nconfig=12 sb2dg01 (or however many copies you want)

regards,

Richard

It simply means that those disks hold the Diskgroup Cnfiguration copies that identifies what disks comprise the diskgroup. 2 disks per diskgroup is usually more than enough IF you are using VxVM with SAN/RAID disks. If JBODs - set it to 3 or even 4 for a little safety net.
