Recovery sequence
To recover from a server or Continuous Access link failure:
1. Start the RAID Manager instances on both local and remote servers:
Linux/UNIX
export HORCMINST=instance_number
horcmstart.sh instance_number
Windows
set HORCMINST=instance_number
HORCMSTART instance_number
2. Gather general pair status information:
pairdisplay –g device_group
3. Display the pair status information after a failed swap-takeover (the S-VOL state is SSWS):
pairdisplay –g device_group –fc
4. To recover from these states, invoke the following command from the S-VOL side:
pairresync –swaps –c 15 –g device_group
If the pair needs to be used on the old primary side, the following commands must be invoked
from the primary side:
pairresync –swapp –c 15 –g device_group
horctakeover –g device_group
