EMC 错了么?
昨天我写到EMC Soft/Hard Read/Write Errors,说EMC建议更换硬盘,可是关于哪一块硬盘产生了分歧.在EMC的Case里,美国专家建议:
Replace drive 0_1_C if not replaced earlier.
因为硬盘编号从0开始C=12,所以我以为应该换的是0_1_13号硬盘,而0_1_13号硬盘也确实是出现错误的一块.可是EMC的现场工程师说0_1_C=0_1_12应该更换0_1_12号硬盘.而0_1_12号一直是没有出现过问题的:
# navicli -h 172.16.9.5 getdisk 0_1_12 Bus 0 Enclosure 1 Disk 12 Vendor Id: SEAGATE Product Id: ST314680 CLAR72 Product Revision: 7A0A Lun: 19 Type: 19: RAID5 State: Enabled Hot Spare: 19: NO Prct Rebuilt: 19: 100 Prct Bound: 19: 100 Serial Number: 3HY6TKCA Sectors: 139681792 (68204) Capacity: 68238 Private: 19: 69704 Bind Signature: 0x13cf, 1, 12 Hard Read Errors: 0 Hard Write Errors: 0 Soft Read Errors: 0 Soft Write Errors: 0 Read Retries: N/A Write Retries: N/A Remapped Sectors: N/A Number of Reads: 209288064 Number of Writes: 12913664 Number of Luns: 1 Raid Group ID: 11 Clariion Part Number: DG118032458 Request Service Time: N/A Read Requests: 209288064 Write Requests: 12913664 Kbytes Read: 1454635954 Kbytes Written: 245519280 Stripe Boundary Crossing: 110585780

结果EMC工程师严格按照建议,更换了0_1_12号硬盘,然后就是热备盘启用:
# navicli -h 172.16.9.5 getdisk 0_0_14 Bus 0 Enclosure 0 Disk 14 Vendor Id: SEAGATE Product Id: ST373307 CLAR72 Product Revision: 7A10 Lun: 101 Type: 101: Hot Spare State: Rebuilding Hot Spare: 101: YES Hot Spare Replacing: 0_1_12 Prct Rebuilt: 101: 100 Prct Bound: 101: 100 Serial Number: 3HZ9E674 Sectors: 139681792 (68204) Capacity: 68238 Private: 101: 69704 Bind Signature: 0x80bd, 0, 14 Hard Read Errors: 0 Hard Write Errors: 0 Soft Read Errors: 0 Soft Write Errors: 0 Read Retries: N/A Write Retries: N/A Remapped Sectors: N/A Number of Reads: 211913765 Number of Writes: 13028867 Number of Luns: 1 Raid Group ID: 101 Clariion Part Number: DG118032459 Request Service Time: N/A Read Requests: 211913765 Write Requests: 13028867 Kbytes Read: 1515830696 Kbytes Written: 247873115 Stripe Boundary Crossing: 0

然后再写回到原盘(Netapp的Host Spare盘是可以漂移的,这个功能很好):
# navicli -h 172.16.9.5 getdisk 0_1_12 Bus 0 Enclosure 1 Disk 12 Vendor Id: SEAGATE Product Id: ST373307 CLAR72 Product Revision: 7A10 Lun: 19 Type: 19: RAID5 State: Equalizing Hot Spare: 19: NO Prct Rebuilt: 19: 100 Prct Bound: 19: 100 Serial Number: 3HZ9ZHWN Sectors: 139681792 (68204) Capacity: 68238 Private: 19: 69704 Bind Signature: 0x13cf, 1, 12 Hard Read Errors: 0 Hard Write Errors: 0 Soft Read Errors: 0 Soft Write Errors: 0 Read Retries: N/A Write Retries: N/A Remapped Sectors: N/A Number of Reads: 1101110 Number of Writes: 2422153 Number of Luns: 1 Raid Group ID: 11 Clariion Part Number: DG118032459 Request Service Time: N/A Read Requests: 1101110 Write Requests: 2422153 Kbytes Read: 145361639 Kbytes Written: 142834423 Stripe Boundary Crossing: 112102090

看来我需要继续跟进这个CASE来确认这个问题了.
