Checking server hard disk status
You can use any of the following methods to check hard disk status: 1. Check each hard disk status indicator. 2. Check hard disk status on the iMana WebUI. 3. Check hard disk status in the Configuration Utility of the RAID controller card.

Method used to check a slow disk
You can check a slow disk as follows: 1. Checking the OSM alarm Check on the OSM management interface whether there is a slow disk alarm whose ID is 5613. If the alarm exist, check whether the slow disk is isolated (the disk has completed reconstruction). If the slow disk is not isolated, refer to relevant disk replacement guides to manually replace the disk. 2. Checking the SES log Collect the SES log of storage devices by obtaining SES_log.txt and bak files under the /OSM/log_conf_local/log/cur_debug directory. Check slow I/O records, I/O distribution, and search keyword Disk IO Delay. --------------------------Disk IO Delay Count------2012-01-10 02:30:52-------------------- Disk IO Delay Count Threshold: [300ms] [500ms] [700ms] [1000ms] [0][2][3LM4JYJJ00009844V79S][3, 5, 15, 1] The above information shows that within five minutes, the disk in slot (0,2) has three I/Os of over 300 ms latency, five I/Os of over 500 ms latency, 15 I/Os of over 700 ms latency, and one I/O of over 1000 ms latency. Longer I/O latency of a disk may result in frequent display of the disk. Refer to relevant disk replacement guides to manually replace the disk. If you have any question, contact technical support engineers. 3. Checking the message log Collect the message log of storage devices by obtaining >message and bak files under the /OSM/log_conf_local/log/cur_debug directory. Search keyword long time. Jun 20 14:45:25 OceanStor kernel: [21086119188]mptscsih SLOW IO INFO: cost long time (13135), host id(0), channel id(0), scsi id (14), lun id(0), io lenth (524288), io mode(1), io lba(0x215321088) The I/O of SCSI device scs id (14) is suspended. Log in to the debug mode of storage devices, enter lsscsi, and obtain the drive letters corresponding to SCSI ID. Log in to the MML mode and enter dev disk enclosure ID to obtain the drive letters corresponding to slot ID. 4. Checking a slow disk If the slow I/O record displays frequently in logs (SES log and message log) and the time when such record is displayed is close to the time when services are affected (such as video freeze), the disk may be the one that affects services and the disk is the slow disk.

How to determine whether an AP is faulty
Determine whether an AP is faulty using the following methods: 1. Check whether the AP indicators are in normal state. For description of AP indicators, see Indicator Description in the Hardware Installation and Maintenance Guide of an AP. 2. Log in to the AP through the console port, Telnet/STelnet, or the web system, and check whether the login succeeds. Fit APs do not support the web system. - If the login succeeds, the AP works properly. - If the login fails, restore the factory settings of the AP by holding down Default, and then log in to the AP again. If a Fit AP has been added to an AC offline, run the display ap all command on the AC to view the AP state. If the AP state is normal or download but not fault, the AP works properly.

Method used to check the copyback information about the disk
Log in to the CLI and run showdisk -e enclosure id -s slot id to view copyback information about the disk. Note: enclosure id indicates the enclosure number of the disk. slot id indicates the slot number of the disk. If copyback is being executed, the copying progress is displayed in the Copyback Progress command output. Take the disk whose enclosure ID is 0 and slot ID is 3 as an example. Run showdisk -e 0 -s 3 to check the copyback information about the disk.
