Dell Power Vault 220S

7th April, 2007
Dell Power Vault 220S raid controller failed and crushed the Exhange databases.
ESE check sum error 1018.
Solution:
1. replace the hardware.
2. move affected mailboxes to a new store.
3. dismount and delete problem stores.

for unmoveable mailbox, dismount store first and then run eseutil /p and eseutil /d command to fix the database problem.
whether have to run isinteg is not sure.
anyway, I did not.
