California Code, Code of Civil Procedure - CCP § 995.960

(1) The court shall specify in what respect the bond is insufficient and shall order that a bond with sufficient sureties and in a sufficient amount be given within five days. If a sufficient bond is not given within the time required by the court order, all rights obtained by giving the bond immediately cease and the court shall upon ex parte motion so order.

(2) If a bond is in effect, the bond remains in effect until a bond with sufficient sureties and in a sufficient amount is given in its place, or the time in which to give the bond has expired, whichever first occurs. If the time in which to give a sufficient bond expires, the original bond remains in full force and effect for all liabilities incurred before, and for acts, omissions, or causes existing or which arose before, expiration.
