Fixed problems Problem AX100SC, AX100SCi - Enclosure LED does not light when the cache card batteries fail to charge. (150862) Details Fixed in Release: 02.19.100.5. 041 Solution: The enclosure LED now lights when the cache card batteries fail to charge. Hardware problems fixed in version 02.19.100.5.035 Problem AX100SC, AX100SCi, AX100, AX100i - Maxtor drive fallout issues. (144052, 146971, 147219, 147908, 148260, 144992, 145764, 147219). Details Fixed in version: 02.19.100.5.035 Solution: Periodically save Smart data to prevent buffer overflows that prevent drives from going online. Hardware problems fixed in version 02.19.100.5.028 Problem AX100SC, AX100SCi, AX100, AX100i - Sniff verify, which helps protect against long-term degradation of the disk media, does not resume after the hot spare swap-out. (141235). AX100SC, AX100SCi, AX100, AX100i - Sniff verify does not work in R19 (140025). Details Fixed in version: 02.19.100.5.028 Solution: Cause sniff verify to restart on a swap-finished operation. Fixed in version: 02.19.100.5.028 Solution: Sniff verify is enabled with this fix. Hardware problems fixed in version 02.19.100.5.018 Problem AX100SC, AX100SCi, AX100, AX100i - If an SP is in degraded mode and is subsequently reimaged, it will enter an endless panic loop. (129619) AX100SC, AX100SCi, AX100, AX100i - AIX uses the fibre open initiator type and fibre open rejects mode sense page 0x3F and mode select page 0xA on the passive path, which results in AIX performing many more reopens than desired during NDU. (130313) AX100SC, AX100SCi, AX100, AX100i - R5 units that are degraded will not log crc or media errors for read I/Os that do not hit the degraded drive position. This leads to missing occurrences of uncorrectable events. (130363) Details Fixed in version: 02.19.100.5.018 Solution: A flag was added to NVRAM that is set when the reboot count is set to zero. This is used as an indication that the count was set to zero on the prior boot and will prevent the count from being set to zero again. This flag will be cleared in NDUMON when the SP is declared to be healthy. Fixed in version: 02.19.100.5.018 Solution: Change made to allow these mode pages to be accepted on the passive path. Fixed in version: 02.19.100.5.018 Solution: Change code to log these errors. EMC AX100-Series Integrated Management Software Release Notes 11
