Ping from within PIX to a vitrual ip address

I have got the pix with this configuration :

ip address outside 10.1.1.130 255.255.255.0
ip address inside 192.168.100.1 255.255.255.0
ip address dmz 192.168.101.1 255.255.255.0

static (dmz,outside) 10.1.1.203 192.168.101.203 netmask 255.255.255.255 0 0
static (dmz,outside) 10.1.1.204 192.168.101.202 netmask 255.255.255.255 0 0
static (dmz,outside) 10.1.1.132 192.168.101.221 netmask 255.255.255.255 0 0
static (inside,dmz) 192.168.101.212 192.168.2.12 netmask 255.255.255.255 0 0


All these ip addresses (192.168.101.202/203/221) in the DMZ area are dedicated for different servers in the dmz area

10.1.1.132/203/204/ are virtual (may be this not the proper name) ip addresses mapped to the DMZ area.

10.1.1.132/203/204,,,refer to the ip addresses in the outside zone

192.168.2.12 for the inside server , while 192.168.101.212 is virtual ip address in the DMZ area

From within the PIX itself, when I tried to ping (virtual ip address I could not), while I was able to ping all other ip addresses (dedicated to a device) :
