No surprise it doesn't work for you, as it by no means fits the problem. Try

Code:
awk '{F[$1] = F[$1] DL[$1] $2; DL[$1] = ","} END {for (f in F) print f, F[f]}' file
B00000 abc
B00001 abc,def,ghi,jkl
B00002 abc,def
B00003 xyz

As the order in which the array elements are retrieved is unspecified, you may need to sort the output. And, you may want to define a different output field separator.

fs_listcells

FS_LISTCELLS(1) 					       AFS Command Reference						   FS_LISTCELLS(1)

NAME

       fs_listcells - Displays the database server machines known to the Cache Manager

SYNOPSIS

       fs listcells [-numeric] [-help]

       fs listc [-n] [-h]

DESCRIPTION

       The fs listcells command formats and displays the list of the database server machines that the Cache Manager stores in kernel memory for
       its home cell and foreign cells.

       At each reboot of the client machine, the Cache Manager copies the contents of /etc/openafs/CellServDB into kernel memory. To modify the
       list between reboots, use the fs newcell command.

OPTIONS

       -numeric
	   Displays each database server machine's IP address rather than hostname.

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT

       The output includes a line for each cell included in the Cache Manager's kernel memory list, in the following format:

	  Cell <cell> on hosts <database server machines>

       The Cache Manager stores IP addresses, but by default has them translated to hostnames before reporting them, by passing them to the cell's
       name service (such as the Domain Name Service or a local host table). The name service sometimes returns hostnames in uppercase letters, or
       an IP address if it cannot resolve a name.

       Using the -numeric flag bypasses the translation to hostnames, which can result in significantly faster production of output. The output
       includes IP addresses only.

EXAMPLES

       The following example shows output for several cells as illustrations of the different formats for machine names:

	  % fs listcells
	  Cell abc.com on hosts fs1.abc.com fs2.abc.com fs3.abc.com
	  Cell stateu.edu on hosts DB1.FS.STATEU.EDU
	     DB2.FS.STATEU.EDU DB3.FS.STATEU.EDU
	  Cell def.gov on hosts 138.255.0.2 sv3.def.gov

       None
