2. Complete the table below by filling in (1a) and (1b) as instructed.

Total No.	/cms size in MB	/cms size in MB
of Disks	(4-GB disks)	(9-GB disks)

2	3104	6208

4	7137	14274

6	11170	22340

8	15203	30406

10	19236

Calculations:

(1a) Enter /cms line’s ‘kbytes’ figure divided by 1000 (move decimal three places left):

(1b) Enter “/cms Size” (above left) corresponding to the number of hard disks and disk size:

(1a)

(1b)

3.Compare the figures in (1a) and (1b). They should be approximately equal. The two will not correspond exactly, but they should be within about 10% of the /cms size figure. A major discrepancy between the disk space you should have and the space recognized by the software usually indicates a connectivity problem. You can check connectivity by checking the output of a metastat command to see that all the disks are recognized. For example:

# metastat
. . .
d21: Mirror
Submirror 0: d19
State: Okay
Submirror 1: d20
State: Okay
. . .
d19: Submirror of d21
State: Okay
Size: 14398560 blocks
Stripe 0:

c0t0d0s3	0	No	Okay
Stripe 1:
Device	Start Block	Dbase State		Hot Spare
c0t2d0s1	0	No	Okay
d20: Submirror of d21
State: Okay
Size: 14398560 blocks
Stripe 0:
Device	Start Block	Dbase State		Hot Spare
c0t1d0s3		0	No	Okay
Stripe 1:
Device	Start Block	Dbase State		Hot Spare
c0t3d0s1		0	No	Okay

If the stripes of d19 and d20 do not account for all the disk drives on your system, check your disk drive connections. If discrepancies persist, telephone the Lucent National Customer Care Center at 1.800.242.2121, or contact your Lucent representative or distributor.
