4 Battery/Flash Backed Write Cache (BBWC or FBWC) module failures

Part numbers

Part numbers for a replacement cache modules are as follows:

G1 products: BBWC = 398648–001

G2 products apart from HP D2D4324: BBWC = 462976–001

HP D2D4324 G2: FBWC = 534562-B21

If replacing this module does not resolve the problem, it may be necessary to replace the RAID controller card. See the appropriate chapter for your RAID card for more information about replacement procedures and part numbers.

Identifying the battery/flash capacitor module failure

Module failures are reported in the Log and, if you have email alerts set up, you will be notified of any failure. The following example illustrates an alert for a failed RAID battery:

HP D2D4324, D2D4312, D2D4106 and D2D4112

The status of the cache module is also reported on the Summary and Storage-RAID pages of the Web Management Interface.

The HP D2D4112 (G2) and the HP D2D4106 have one battery only. (The HP D2D4112 G1 has two batteries, both on the one controller.)

The HP D2D4324 has four flash capacitor modules and the HP D2D4312 has three batteries; one for each RAID card. The Summary page shows that there is a flash capacitor module or RAID battery failure, but does not identify the card to which it belongs. Look at the Storage-RAID page to identify the card. The P410i card is identified as internal; the three P812 (HP D2D4324) and two P411 (HP D2D4312) cards are identified by their slot location.
