         Hi,

I've a raid5 diskgroup made of 8 18Gb physical disks. I've 2 disks that
went down. So I removed them for the raid diskgroup.
You can see that with this 'vxprint' output :

Disk group: raid5dg

TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0
PUTIL0
dg raid5dg raid5dg - - - - - -

dm raid5dg01 - - - - REMOVED - -
dm raid5dg02 c2t11d0s2 - 35358848 - - - -
dm raid5dg03 c2t12d0s2 - 35358848 - - - -
dm raid5dg04 c2t13d0s2 - 35358848 - - - -
dm raid5dg05 c2t2d0s2 - 35358848 - - - -
dm raid5dg06 c2t3d0s2 - 35358848 - - - -
dm raid5dg07 - - - - REMOVED - -
dm raid5dg08 c2t5d0s2 - 35358848 - - - -

v data_03 raid5 DETACHED 247511040 - ACTIVE - -

sd raid5dg01-01 data_03-01 DISABLED 35358848 0 REMOVED - -
sd raid5dg02-01 data_03-01 ENABLED 35358848 0 - - -
sd raid5dg03-01 data_03-01 ENABLED 35358848 0 - - -
sd raid5dg04-01 data_03-01 ENABLED 35358848 0 - - -

But now, I can't manage to bring the volume up.

root@rogue# vxvol resync data_03
vxvm:vxvol: ERROR: Volume data_03 is not started
root@rogue# vxvol start data_03
vxvm:vxvol: ERROR: Volume data_03 is not startable; Raid5 plex does not
map the entire volume length

Any ideas ?
Thanks in advance. Best regards.
