Hello! I encountered a problem with the HGST s840 (Model Number = Z16IZF2E-2TBUCZ-VZ) disks falling off on a Dell PERC H740P controller. Currently, the disks have non Dell Firmware Revision = C22F installed. Can anyone share the firmware files and utilities for this? I probably need the E4Z1.G4-SK04-72R35-YN-v4.0.4.RC11-b1975 described in this post. At the moment, all links are dead. Thank you in advance for your help.hello,
good news coming - i have a working recipe howto repair drives and therefore fix the mentioned speed degradation.
1) you need to download some files from Index of /public/hgst_2tb/util
2) update drive firmware (maybe not necessary, but wise) - scan is needed, without scan hdm can't update firmware
- E4Z1.G4-SK04-72R35-YN-v4.0.4.RC11-b1975 - newest firmware
- hdm-core_3.4.0-8.ga_amd64.deb - utility for loading firmware
- sdmcmd64.2.0.0.124.tar.gz - utility for STEC drives
- smartmontools-6.0-stec.tar.gz - modified smartmontools which can read extended STEC info
3) use sdmcdm64 utility and scan for available drivesCode:hdm scan [5000A72030097FE9] Device Type = SCSI Device Device Path = /dev/sdd UID = 5000A72030097FE9 Alias = @scsi0 Vendor Name = STEC Model Name = Z16IZF2E-2TBUCZ hdm manage-firmware --load --activate --file E4Z1.G4-SK04-72R35-YN-v4.0.4.RC11-b1975 --path /dev/sdd Results for manage-firmware: Operation succeeded.
4) use sdmcdm64 utilty to clear SMART errorCode:./sdmcmd64 scanLocal Results for ScanLocal operationResult = Success devices.count = 7 devices[0] = other:Drive0 devices[1] = gen4sas:Drive6 devices[2] = gen4sas:Drive5 devices[3] = gen4sas:Drive4 devices[4] = gen4sas:Drive3 devices[5] = other:Drive2 devices[6] = other:Drive1
5) use sdmcdm64 utility to format the drive. it's needed to do format twice - after first format the drive reports zero size (0 sectors capacity),Code:./sdmcmd64 ClearSmartAlerts target=gen4sas:Drive3 Results for ClearSmartAlerts operationResult = Success target = gen4sas:Drive3
but after second format everything will be ok and drive gets his 2TB capacity back.
you can see how long takes first format - 1 minute and 42 seconds and how long takes the second format - only 4 seconds..
6) check the formatted drive, it should look like followingCode:time ./sdmcmd64 Format target=gen4sas:Drive3 sectorSize=512 difLevel=None Results for Format operationResult = Success target = gen4sas:Drive3 real 1m42.699s user 0m0.000s sys 0m0.005s time ./sdmcmd64 Format target=gen4sas:Drive3 sectorSize=512 difLevel=None Results for Format operationResult = Success target = gen4sas:Drive3 real 0m4.739s user 0m0.003s sys 0m0.002s
Now the drive is back in good state, no speed probles, no errors.Code:./sdmcmd64 GetDriveSize target=gen4sas:Drive3 Results for GetDriveSize operationResult = Success target = gen4sas:Drive3 hostBlocks = 3907029168 userBlocks = 6821 0x1aa5
That's all. So easy it is
Even if it now looks easy and simple, the way to this recipe was relativeluy long and time consuming..
